The main difference between Achilles tendonitis and fasciitis is that they occur in different locations. Achilles tendonitis is mainly in the Achilles tendon, while fasciitis can occur anywhere in the body where fascia exists, which is a fundamental difference. Both Achilles tendonitis and fasciitis are localized aseptic inflammation and are usually treated in a similar way. They require less exercise, rest, protection, and no cold, localized hot compresses, and topical ointments that activate blood circulation and resolve blood stasis, such as blood pain cream and Yunnan Baiyao cream. In addition, non-steroidal anti-inflammatory and analgesic drugs can be taken orally to relieve the pain symptoms caused by sterile inflammation, such as ibuprofen extended-release capsules and nimesulide capsules, which are very effective. Patients with more definite pain points can have local closed injections, usually with lidocaine and prednisolone acetate.
