If a lump is found at the root of the thigh, it may be a local lymph node inflammation with swollen lymph nodes; it may also be other masses, such as the masses protruding from a hernia, and you can go to the hospital in time to see a doctor for an interview, who will make a preliminary judgment by combining the examination with the body. If the mass is considered to be caused by inflammation of lymph nodes, local ultrasound examination can be improved. For lymph node inflammation, you can choose anti-inflammatory drugs and other treatments. If it is a local hernia mass, surgery can be chosen to repair it. There may also be others, such as localized tuberculosis, cold abscess or lipoma masses, and further magnetic resonance imaging is required if necessary. Depending on the results of the examination, further treatment such as surgery or anti-tuberculosis will be performed to help recovery.
