Hello!
It may be gynecological inflammation, such as vulvitis, vaginitis, cervicitis, cervical erosion, etc., which will secrete some irritating secretions and cause vulvar itching. I suggest you pay attention to cleaning, change your underwear frequently and use water at ordinary times. It may be other skin diseases, such as neurodermatitis or eczema.
There are many possibilities of vulvar itching. It is recommended to go to the hospital instead of taking medicine yourself, so as not to aggravate the condition and delay treatment.
I wish you the best of health!
Disease analysis:
At present, it is believed that itching and pain are transmitted through the same neural pathway. Itching, like pain, is stimulated by the free spirit at the junction of epidermis and dermis through the peripheral network. It is connected with the brain through afferent and efferent nerve reflexes. Whether the stimulus is external, internal, reactive or reflective, it will induce itching.
It is a basic but physiologically active medium between the stimulus that causes itching and the impulse that occurs at the free nerve endings. Histamine is the material basis of itching. Any factors that cause mast cells to be stimulated, such as allergy, body and spirit, can make mast cells degranulate and release histamine. Therefore, antihistamines and drugs that stabilize mast cells to reduce histamine release can be used to treat histamine-induced itching.
Peptide is a kind of hydrolyzed protein, and bradykinin may also be the medium for allergic skin diseases to produce itching and wheal.
Prostaglandin and its related substances, inflammatory cells in human skin are related to arachidonic acid metabolites. These substances include prostaglandin, polymorphonuclear leukocyte chemokine and leukotriene. It is found that prostaglandin itself can not cause itching, but it can lower the threshold of skin itching caused by histamine, thus aggravating itching. It is not clear whether leukocyte chemokines and leukotrienes can enhance itching caused by other inflammatory mediators.
Environmental and local factors will directly affect the skin's sensitivity to itching stimuli. When the skin temperature rises slightly, the itching will be aggravated. For example, hot water bathing, high room temperature, fire or exercise can stimulate nerve endings to cause itching, and excessive humidity in the air can also cause dry skin, which is more obvious in the elderly.
Mental and emotional instability can also increase the sensitivity of itching. Eating too much spicy food, drinking alcohol and drinking coffee can all cause itchy skin.
In addition to itching caused by many skin diseases, itching also occurs in some systemic diseases. For example, uremic itching is related to a circulating factor in the body, and obstructive jaundice can cause intractable itching.
In a word, the mechanism of itching is very complicated, and the exact mechanism is still unclear.
There are many kinds of skin diseases that cause itching. Because the severity and degree of individual damage are different, even patients with the same skin disease feel different. Even patients with the same skin disease have different feelings. The causes of itching are complicated, and some of them are still unclear. Now we will classify the common itchy or severe itchy skin diseases as follows.
(1) Infectious dermatosis
1. Viral dermatoses such as chickenpox, measles and verruca plana.
2. Bacterial dermatosis, pustulosis, folliculitis, etc.
3. Fungal dermatoses: tinea capitis, tinea pedis, tinea corporis, tinea cruris, tinea versicolor, etc.
4. Parasites and animal skin diseases, such as hookworm dermatitis, schistosomiasis dermatitis, crawling rash, lice disease, mosquito bite, mite dermatitis, caterpillar dermatitis, scabies, etc.
(2) Physical dermatosis
Rash, polymorphous solar rash, solar dermatitis, chilblain, rubbing lichenoid rash, etc.
(iii) Allergic dermatosis
Contact dermatitis, eczema, atopic dermatitis, allergic dermatitis, seborrheic dermatitis, drug eruption, urticaria, papular urticaria.
Neurofunctional dermatosis
Neurodermatitis, pruritus, prurigo nodosa, prurigo gravidarum, exudative discoid dermatitis and lichen dermatitis.
(5), scarlet fever-like erythema, erythema multiforme, psoriasis, parapsoriasis, pityriasis rosea, pityriasis folliculorum, papulosis gravidarum, lichen planus, lichen sclerosus, erythroderma.

Guiding opinions:
Extractable nuclear antigen (ENA)
The extractable nuclear antigens are mainly anti-ribonucleoprotein (RNP) antibodies and anti-Sm antibodies.
Rheumatoid factor (RF)
Rheumatoid factor is an autoantibody against human denatured immunoglobulin in the serum of patients with rheumatoid arthritis and other diseases.
corticotrophin
Adrenocorticotropin is a trace polypeptide hormone secreted by pituitary gland and the main regulator of adrenocortical activity.
Serum aldosterone (ALD, ALS)
The function of aldosterone is to promote sodium reabsorption and potassium excretion of renal distal convoluted tubule epithelial cells. The secretion of aldosterone is similar to that of cortisol day and night, and it is lower in the morning than at night. Standing position is more than lying position, and its plasma concentration changes accordingly.
estradiol
Estradiol (E2) is mainly produced by follicles, corpus luteum and placenta during pregnancy. Detection of serum and urine estradiol is valuable for the diagnosis of endocrine and gynecological diseases such as precocious puberty and dysplasia.
Procaine intradermal test-
The intradermal test should be carried out before procaine injection to prevent allergic reaction during injection.
Penicillin intradermal test-
Intradermal test of allergic reaction should be done before injection to prevent allergic reaction during injection.
Streptomycin intradermal test-
Intradermal test should be done before streptomycin injection to prevent allergic reaction during injection.
Urogen (URO)
Bilirubin in urine includes bilirubin, urinary urobilinogen and urobilin, commonly known as urobilin. Because most urine is fresh and urobilin is not oxidized into urobilin, the first two are commonly known as urobilin. Urbilin turns yellow after air oxidation and light exposure.
Urinary bilirubin (BIL)
Bilirubin is produced by metabolism after red blood cells are destroyed. It can be divided into unbound bilirubin without liver treatment and bound bilirubin formed by the combination of liver and glucuronic acid. Unbound bilirubin is insoluble in water and cannot pass through the glomerular filtration membrane when combined with protein in blood. Conjugated bilirubin has small molecular weight and high solubility, and can be excreted from urine through glomerular filtration membrane. Because the content of conjugated bilirubin in normal blood is very low and the filtration volume is very small, bilirubin can not be detected in urine. If the bound bilirubin in the blood increases, urine can be generated through the glomerular membrane.
urobilin
Urine bilirubin includes bilirubin, urine urobilinogen and urine urobilinogen. Because most urine is fresh, urine urobilinogen is not oxidized into urine urobilinogen, so urine bilirubin and urine urobilinogen should be checked clinically.
Neuron-specific enolase
Neuron-specific enolase (NSE) is an acid protease unique to neurons and neuroendocrine cells, and it is the most sensitive and specific tumor marker of small cell lung cancer (SCLC).
Disease analysis:
In this case, I suggest you change a kind of toilet paper to see if it can improve the symptoms. It is best not to use scraps of paper, and the brand with guaranteed hygiene.
Guiding opinions:
If it's not the toilet paper itself, it should be your problem. It may be inflammation of vagina or vulva. You need to do routine leucorrhea examination to determine what kind of pathogenic bacteria it is, and then the doctor will choose drugs sensitive to pathogenic bacteria for treatment according to the examination results.
Disease analysis:
It itches when you wipe your genitals with toilet paper, but it doesn't itch if you don't wipe it!
Guiding opinions:
Maybe your vulva is allergic to toilet paper! I suggest you use another kind of paper or wet wipes or try other ways to minimize the contact of paper towels! Also pay attention to vulva cleaning and regular cleaning! But don't be too diligent, 1 lest it destroy its own protection mechanism!
Life care:
I wish you good health and all the best!
Disease analysis:
Female pudendal pruritus is a common symptom, which not only affects daily life and work, but also may lead to marital discord and even other diseases. The main causes of pudendal itching are as follows:
1, local skin uncleanness can cause pudendal itching: some women do not do well in hygiene, which leads to chronic inflammation of pudendal skin caused by menstrual blood, vaginal secretions and even urine, feces and sweat, thus causing pudendal itching.
2. Trichomonas vaginalis infection: the female vaginal environment is acidic. When the acidity of female vaginal mucosa environment decreases, the production of lactic acid decreases, which is easy to breed and infect Trichomonas vaginalis, showing foamy leucorrhea and pudendal itching.
3, mold infection: If women suffer from diabetes or long-term use of antibiotics will cause normal flora imbalance, Candida albicans in mold will easily take the opportunity to invade vulva and vagina, resulting in vulva mold and vaginitis, often with symptoms of bean dregs-like leucorrhea and pudendal itching.
4. Parasitic infection: When the anus is relaxed at night, the pinworm will crawl out of the rectum and swim to the genitals to mate and lay eggs, which will stimulate the skin and mucosa of the genitals and cause local itching. Scabies infection can cause scabies, and external skin lesions will be very serious, so local itching is also the most obvious. Pubic lice infection is a common cause of pudendal itching; It is characterized by severe itching of pubic hair, and prickly heat or lice the size of gray millet can be seen at the root or hair shaft of pubic hair.
5, drug eruption: allergic women taking sulfonamides or other drugs caused by "fixed drug eruption", often occurs at the junction of pudendal skin and mucosa, in addition to local itching, can be complicated by erosion, exudation. Vaginal pruritus can also occur when drugs are used for vaginal irrigation or vaginal implantation, such as allergic reaction and contact dermatitis.
6, pudendal itching caused by pudendal skin disease: the skin damage of tinea cruris often extends to the pudendal part, causing local severe itching. The local itching caused by pudendal eczema and neurodermatitis is more serious. The former is characterized by papules, blisters and erosive exudates with unclear local skin boundaries, while the latter is often accompanied by moss caused by skin thickening and scratching. In addition to local itching, vulvar leukoplakia is often accompanied by vulvar malnutrition and skin atrophy.
7. Virus infection: Condyloma acuminatum mostly occurs in women's vaginal wall, cervix and vulva, and there is also a foul leucorrhea. Infectious molluscum that occurs in vulva is mostly characterized by round papules with umbilical fossa depression in the center, which can also cause pruritus in vulva. Genital herpes (special interview and consultation) is mostly manifested as bright blisters the size of rice grains at the urethral orifice and vaginal wall except local itching.
8. Other causes of pudendal itching:
When women suffer from diabetes, due to the stimulation of urine sugar on vulva skin, toxic vulva and vaginitis are easily complicated, causing pudendal itching. When jaundice occurs due to diseases such as liver and gallbladder, the skin can also be itchy due to the increase of red substances in blood bladder and the stimulation of bile salts. In addition, some women will also cause pudendal itching due to psychological factors when they are nervous.
Guiding opinions:
Female pudendal itching, keep pudendal skin clean and dry, do not scratch or itch, and do not eat spicy or allergic food.

10, itchy sore. Use one or two purple bamboo shoots, half two peppers, decoct and wash warmly, and it will be fine for several times.
Women with pudendal pruritus should pay attention to keeping pudendal skin clean and dry, and underwear should be loose and breathable. Don't scrub with soapy water or irritating detergent, don't scratch and relieve itching, and don't eat spicy and allergic food.
1. local causes 1) fungal vaginitis and trichomonal vaginitis are the most common causes of vulvar itching. Lice and scabies can also cause itching. Itching around anus and vulva caused by pinworm usually only occurs at night.
Chronic vulvar dystrophy is characterized by itching, accompanied by whitish vulvar skin.
Drug allergy or chemical crystals stimulate soap, condoms and mercuric chloride, which can cause contact dermatitis and itching symptoms due to direct stimulation or allergy.
4) Poor hygiene habits, not paying attention to the local cleaning of vulva, sebum, sweat, menstrual period, vaginal secretions, and even urine and feces soaking can cause itching for a long time: using rubber or plastic menstrual belt during menstruation and wearing airtight chemical fiber underwear at ordinary times can cause itching due to damp heat stagnation; 5) Other skin lesions, abrasions, common warts, herpes, eczema and tumors can all cause vulvar itching.
Clinical manifestations and diagnosis of pudendal pruritus
Vulvar pruritus is mostly located in clitoris and labia minora, and can also spread to labia majora, perineum and even perianal lesions. Often paroxysmal or persistent, generally aggravated at night. Unreasonable vulvar pruritus generally only occurs in women of childbearing age or postmenopausal women, involving the whole vulva, but it may also be limited to a certain part or unilateral vulva. Although itching is very serious and even unbearable, the appearance of local skin and mucosa is normal, or just because of excessive scratching.
Treatment of pudendal pruritus
First, general treatment should pay attention to menstrual hygiene, keep the vulva clean and dry, avoid scratching, do not use hot water to wash and iron, and do not use soap. If there is infection, potassium permanganate solution can be used for sitz bath, but local scrubbing is strictly prohibited. Clothes, especially underwear, should be comfortable and breathable. Avoid alcohol and spicy or allergic food.
Second, etiological treatment can eliminate local or systemic factors that cause itching, such as trichomonas, fungal infection or diabetes. Third, the symptomatic treatment (1) can use 1% Rizzo singa 1 foil, rivanol solution, or 30%; Wet application of boric acid solution, and local application of 40% oxide paste after washing; Chronic itching can be wiped with corticosteroid ointment or 2% diphenhydramine ointment. (2) When the medical symptoms are serious, chlorpheniramine 4mSt diphenhydramine 25mg or isoproterenol 25ml can be taken orally to achieve the dual effects of sedation and desensitization.
Disease analysis:
According to your description, there is no need for treatment, just local sensory abnormalities, and generally the distraction disappears.
Guiding opinions:
Minimize local irritation. Generally, do not stimulate the local area with hot water, and do not scratch it. If necessary, go to gynecology or dermatology for physical examination to see if there are any organic lesions, and then make a treatment plan.
