Plantar fasciitis is the medical term for plantar fasciitis. It is a chronic aseptic inflammation that occurs in the plantar fascia at the attachment of the calcaneal tuberosity, mainly due to prolonged walking or running, which puts the plantar fascia or muscles in a state of high load for a long period of time, and causes repetitive pulling injuries to the plantar fascia and its stopping point. The aim of treatment is to completely eliminate pain, and conservative treatment is the mainstay, which usually takes 4 weeks to 18 months. 1. Oral medication: The overall goal of medication is to reduce pain, restore the normal function of plantar tissues and structures, and prevent complications. In addition to commonly used over-the-counter medications, the most appropriate medication should be selected under the guidance of a doctor in full combination with individual circumstances, such as commonly used oral medications include non-steroidal anti-inflammatory drugs such as ibuprofen and corticosteroid injections (closed treatment), which can be used in combination with physical therapy. 2. Physical therapy: such as extracorporeal shock waves can reduce tissue edema, reduce plantar fascia tension, but also to a certain extent to repair the degenerative tissues, thereby relieving pain. In addition, there is also high-frequency electrotherapy. 3. Wearing functional insoles: made according to different individual plantar morphology and special physiological curvature of the foot arch, the plantar pressure during walking or exercise is evenly distributed to the ball of the foot in order to relax the plantar muscles, reduce the tension of the plantar fascia, and promote the dissipation and absorption of inflammation, thus achieving the purpose of relieving pain and promoting the restoration of normal function. Conservative treatment is a long process, patients need to adhere to the treatment plan, for conservative treatment is not effective patients need to be under the guidance of the doctor for local closed treatment or surgical treatment. The above drugs need to be used under the guidance of a doctor, avoid self-medication.
