Small wounds can also cause scar hyperplasia! Mr. He, a 34-year-old man, was cut on his chest by a necklace many years ago. After the wound healed, a dark red lump gradually appeared and was ignored. Recently, I went to the hospital because of itching and pain. Unexpectedly, after examination, it was found that the dark red lump on the chest was actually the outward expansion and proliferation of scars, which caused the crab's feet to swell. Later, I saw a doctor, applied local pressure with beauty tape, and cooperated with topical drugs to relieve itching and pain. The discomfort symptoms have been relieved.

Scar becomes bigger, bigger, with tingling and itching? Beware of the trouble caused by "swollen crab feet"

Huang Jiyi, chief physician of plastic surgery department of Shu Tian Clinic, said that scar is an inevitable product in the process of post-traumatic repair. When the depth of injury reaches the dermis, the skin surface may leave scars. Especially, if people do not take good care of scars after injury, it may lead to scar hyperplasia (excessive proliferation of skin fibrous connective tissue), accompanied by smooth, ruddy and shiny protrusions and telangiectasia around the wound.

Small wounds can also cause scar hyperplasia! If people do not take good care of scars after injury, it may lead to scar hyperplasia (excessive proliferation of skin fibrous connective tissue). Once the scar grows to the edge of the original skin damage, it will protrude like a crab's foot, which is also commonly known as "crab's foot swelling." Common in the upper arm, upper back, shoulder and chest skin tension or joint activity, as well as wounds that hurt the dermis.

Clinically, the causes of edema of crab feet are mostly related to physical or genetic factors, trauma and other factors; It usually happens when the wound heals, but it may also happen long after the injury. Dark red protrusions will appear in the initial wound, and then it will expand and proliferate outward, accompanied by uncomfortable symptoms such as tingling and itching; If it occurs in joints, it is more likely to cause mobility inconvenience in severe cases.
