Treatment of Achilles tendonitis includes general treatment, medication, physical therapy and surgery. 1. General treatment: When the pain attacks, pay attention to rest, stop or reduce physical exercise, and use a brace to support the cartilage. When pain symptoms occur, local cold compresses can be used to relieve pain symptoms. 2. Medication: Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used to relieve severe pain caused by Achilles tendonitis, such as ibuprofen and celecoxib. When the local swelling and pain are serious, glucocorticoid combined with lidocaine can be chosen for closed treatment. 3. Physiotherapy: It is used for auxiliary treatment, including electric stimulation therapy, ultrasound therapy, laser therapy, shock wave therapy, etc., which can eliminate local swelling and pain. 4. Surgery: If the Achilles tendonitis caused by excessive tension in the gastrocnemius muscle cannot be recovered through conservative treatment, gastrocnemius muscle lengthening surgery is needed to relieve the tension in the gastrocnemius muscle. If the disease is serious, it is necessary to carry out cleaning and repair of the lesion treatment. If the diagnosis of Achilles tendonitis is confirmed, it is necessary to consult a doctor in a timely manner, please standardize the treatment under the guidance of the doctor.
