Local hyperplasia: When the affected area (especially the growth of the abdomen and back, hands and feet, etc.) is subjected to long-term friction, pressure and other external stimulation, local skin tissue hyperplasia is very likely to occur, which will show the tactile sensation of the flesh bumps. If there is no trend of growth and no pain or itching, it can be considered as benign hyperplasia. If the “flesh bumps” continue to grow, and the growth of rapid, itching, pressure and pain and other symptoms, is considered to be a malignant tumor, patients need to consult the doctor in a timely manner, relevant pathological examination to clarify the condition; serious cases need to be removed in a timely manner, so as not to continue to stimulate or malignant changes. 2. Local trauma infection: if patients scratch the affected area with bare hands, resulting in skin breakage, it is very easy to cause infection, inflammation and so on, showing local tissue redness and swelling. It is recommended that the patient consult the doctor in a timely manner, carry out relevant examinations, clarify the cause of the disease, and then receive targeted treatment.
