Little toe pain may be caused by gout, pressure injury, tumor and other reasons. 1. Gout: Uric acid salts in gout patients will be deposited in the bone and joint parts of the toes, exerting pressure on the tissues at the joints and causing pain in the bunion. 2. Pressure injury: Due to ill-fitting shoes or shoes that are too small, the bunion will rub against the shoe surface for a long period of time and suffer from extrusion, which will cause soft tissue injuries and lead to pain in the bunion. 3. Tumor: Bone tumors occurring in the bunion, tumor tissue erosion of peripheral nerves or compression of normal tissues around the bunion, can cause bunion pain. There are many other reasons for bunion pain, so patients should go to the hospital in time to improve the examination and give targeted treatment after clarifying the cause of the disease, so as to avoid further progression of the disease.
