Hard knots around the umbilicus can be caused by subcutaneous lymph nodes, epidermal cysts, lipomas, etc. There is usually no way to rub them away. The appropriate treatment should be taken according to the cause of the disease. 1. Subcutaneous lymph nodes: If the lymph nodes are normal, not infected, no pain, usually can not be touched, do not need treatment; if there is lymph node inflammation caused by swelling, you can take oral cefuroxime tablets, amoxicillin capsules and other antibiotics and other anti-infective treatment. 2. Epidermal cysts: these are cysts formed when the cells of the basal layer of the epidermis enter and grow under the skin, which usually need to be removed surgically. 3. Lipoma or subcutaneous fibroma: most of them are benign tumors formed by differentiation and proliferation of mature adipose tissue or fibrous tissue abnormality under the skin, generally no special treatment is needed, if it affects the function, appears to be compression manifestation, or grows rapidly, then surgical excision can be considered. If you find hard nodules around the umbilicus, you should go to the hospital in time, and follow the doctor’s instructions for treatment after a clear diagnosis, and you should not rub and scatter them randomly.
