During the onset of Achilles tendonitis, it is not recommended to play ball games or other high-intensity sports, and should be actively treated with rest, but if the condition recovers well, sports can be resumed gradually. Achilles tendonitis is an aseptic inflammation of the Achilles tendon, caused by prolonged repetitive or strenuous stretching that exceeds the load of the Achilles tendon. Continuing to play during the onset of Achilles tendonitis will lead to increased discomfort in the Achilles tendon area, and may even lead to aggravation of the inflammation, affecting the surrounding tissues, causing osteomalacia or bursa calcification and other conditions to further aggravate the condition, which is not conducive to the recovery of the organism. Patients with Achilles tendonitis should control the amount of exercise during the onset of the disease, reduce the Achilles tendon pulling, and stop exercising if necessary. Patients with Achilles tendonitis can take non-steroidal anti-inflammatory drugs, such as diclofenac, celecoxib, etc. and glucocorticosteroids under the guidance of a professional doctor to relieve pain and swelling, and at the same time can be combined with ultrasound, ice and other physical therapy to restore health, and can be taken to the surgery if necessary. It is recommended that patients with Achilles tendonitis consult a doctor in a timely manner, actively cooperate with the doctor’s treatment, and do not take medication without authorization in order to avoid delays or adverse reactions.
