An abscess on the inner thigh is an infectious disease, of bacterial origin. It can be an acute infection or a chronic one. It can develop from the spread of a local infection to an abscess, or it can be an abscess that develops due to an infection in another part of the body and blood transport to the inner thigh. It can present the following symptoms: 1. Localized pain. It is often accompanied by a feeling of swelling and pain, localized redness of the skin, increased skin temperature and obvious pressure pain, which are the characteristic signs of the infection. 2. Restriction of movement. When an abscess appears on the inner thigh, the patient should undergo early antibiotic treatment. If the antibiotic treatment is not effective, or if the fever persists and the local abscess gradually increases, surgical operation should be performed to incise and drain the abscess.
