What is swollen crab feet?
Some people may have the experience that the wound grows around like a "crab's foot", so it is called crab's foot swelling. At first glance, it looks like a raised scar, which affects the appearance. But over time, some people's "crab feet" will grow into "crab meat" and become a big piece. At this time, there may be symptoms of itching and pain, not just problems that affect the appearance.
Simply put, crab's swollen feet are an excessive repair to the body. When the wound heals, it will grow new skin while repairing the old necrotic skin. When these two come out and go in, it is reasonable to achieve balance, smooth skin and a little bump at most; However, when the body is repairing, too many repair cells are produced, but they are not completely metabolized, which will make the scar fat and thick, and you can obviously feel the swelling.
Huang Jiyi, chief physician of the Plastic Surgery Department of Shu Tian Clinic, said, however, the general growth range of "scar hyperplasia" is the original position of the wound, and there will be no more, but the swelling of the crab's foot will "climb out" with the crab's foot, and the longer it is, the bigger it will be, and even the surrounding skin will begin to proliferate; Some people even have a table tennis ball swollen on their ears because of a small wound like pricking their ears. If the masses grow on the joints, even their activities may be restricted.
Why do crabs have swollen feet?
As mentioned above, the occurrence of crab foot swelling is because the body's repair mechanism is too active, so it is particularly related to physique. Clinical statistics show that 5 ~ 10% of patients with crab's foot swelling have related family history, which also makes it difficult to treat crab's foot swelling.
But another reason may be that the injured skin is always pulled by external forces, for example, the chest will swell due to breathing, and the joints are often pulled; In addition, where the skin is thick and the muscle activity is large, the collagen mother cells repaired by * * * are active, which makes it easier to proliferate scars, such as arms, shoulders and outer thighs.
The study also found that apart from family history, young people between 10 and 30 years old, people with type A blood and colored people are more likely to have swollen crab feet, and even squeezing a pimple, mosquito bites, ear piercing and even acupuncture may hurt the dermis, leading to swollen crab feet; Redness and swelling may not happen now, and it will only happen weeks or even years later. You can't prevent it, you can only be careful not to get hurt and take good care of the wound.
What should I do if the crab's foot is swollen?
At present, there is no complete cure for crab's foot swelling, and the recurrence rate is high, but the tumor can be shrunk by injecting steroids, laser therapy, surgery, radiotherapy and other methods. , so as not to interfere with daily life and beauty; However, steroids and other drugs can cause other normal skin atrophy and microvascular hyperplasia around, so we should also discuss it carefully when using it. Maybe we can switch to cryotherapy, and in the same medical insurance coverage, freeze the skin to inhibit tissue proliferation.
In addition, some pressure can be applied to the skin by sticking silica gel membrane to reduce the blood flow and oxygen of scar tissue and inhibit excessive proliferation. Some people say that scars can dilute scars, which is the method used, but the key is to put pressure on scars, so "lateral massage" is not effective and needs "longitudinal pressing".
Huang Jiyi also mentioned that if you are injured, you can take more protein and vitamin C to make the wound heal faster, and try not to touch the wound, because every time you pull, you are telling your skin that you are injured, so the scar is more likely to proliferate.
