traumatic
Fracture of coccyx
The main symptom of coccyx fracture caused by external force is coccyx pain. Because the coccyx is the only vertebra without weight, the pain symptoms are not obvious when walking, but obvious when sitting because of gravity compression.
Contusion of tissue around sacrococcygeal region
Under the action of external force, the tissue around sacrococcygeal bone is injured, and its symptoms are mainly oozing blood and edema at the injured part, which is characterized by severe pain, congestion, swelling and congestion of coccyx.
Childbirth injury
During pregnancy and childbirth, it is easy to cause sacrococcygeal displacement and peripheral tendon strain and sprain, which is characterized by pain in the musculoskeletal ligament of coccyx and its surrounding soft tissue and difficulty in sitting.
infect
Tuberculosis of coccyx
At first, the pain is mild, and the pain points are not limited. With the progress of the disease, the pain point is fixed on the diseased part of the coccyx. In addition, perianal infection is characterized by abscess, but there is no local redness and fever, that is, cold abscess, accompanied by coccyx tenderness and low fever.
degenerative disease
Lumbar spondylolisthesis
The clinical manifestations are progressive pain below the waist, and the lower waist can touch the feeling of steps, often accompanied by radiation pain and numbness of one or both lower limbs.
Hyperplasia of coccyx
The symptoms are mainly pain, which is gradual. In daily overwork or local overstimulation, especially sedentary, it will lead to aggravated pain.
Chronic strain
Strain of sacrococcygeal tendons and ligaments
It is found in workers who bend over their desks for a long time. The symptom is that the sacrococcygeal pain will be aggravated when sitting or standing up from the sitting position every day, but there are no symptoms of hip soft tissue such as swelling, fever and cyanosis.
tumour
Primary bone tumor
Sacrococcygeal tumors grow rapidly, mostly showing pain, while benign tumors have fewer symptoms. Malignant tumors are mostly local pain, which starts with intermittent and slight coccygeal pain and gradually develops into persistent severe pain, accompanied by night pain and tenderness. If there is a fracture during the period, the pain will suddenly increase.
Metastatic bone tumor
Metastasis of cancer to coccyx or sacrococcygeal bone is a kind of increasing deep pain, which gradually changes from intermittent pain at first to persistent pain, such as spinal metastasis, often accompanied by fractures.
