The most common cause of fever and pain on the bottom of the foot is plantar fasciitis, which is common in patients with flat feet or chronic sterile inflammation of the musculofascial and bone caused by long-term strain and chronic exertion during the day. Plantar fasciitis is mainly relieved by conservative treatment, which includes reducing foot movement and walking distance, paying attention to the warmth of the affected foot, and choosing appropriate soft-soled shoes. When the symptoms are more severe, appropriate oral non-steroidal anti-inflammatory drugs and blood circulation drugs can be taken to improve the symptoms. If some patients want to cooperate with some physical therapy, they can take acupuncture, baking lamp, microwave to promote local blood circulation and improve the symptoms. If the symptoms do not improve significantly, you can also try to use closure therapy. In a few patients, if the above conservative treatment is not effective, surgical treatment can be used. The purpose of surgical treatment is to loosen the adhesions of tendons and endings.
