In clinical practice, tendonitis of the great toe of the foot is often seen in patients. It is mainly caused by overexertion, strain, and cold in the patient. The specific treatment depends on the degree of tenosynovitis and the clinical presentation of the patient. If the degree of tenosynovitis is mild, the patient only feels localized pain and positive pressure pain, but the toe can move, and the patient can even walk with weight. Conservative treatment can be given by local braking and avoiding local exposure to cold. Local physiotherapy such as acupuncture, moxibustion, and acupuncture point herbal iontophoresis can be performed to accelerate local blood circulation. If the patient feels that the tendinitis in the bunion area is more painful, the skin is red and swollen, and walking with weight is limited, which affects the patient’s normal life. Surgery can be considered to do an incisional tendon sheath release, which also requires the patient to rest in bed after surgery.
