Tendinitis refers to the condition where, due to excessive flexing and extending movements, adhesions, exudation, and fibrosis occur between the tendon and the tendon sheath, leading to a local aseptic inflammatory response. This results in symptoms such as pain and limited mobility. When tendinitis occurs, it is important to choose the appropriate treatment based on the symptoms, such as adequate rest, avoiding excessive activity, and using physical therapy and heat applications to reduce local inflammation. If necessary, non-steroidal anti-inflammatory and analgesic drugs can be used for symptomatic treatment. However, massage does not have a significant effect, and a suitable and systematic treatment approach should be selected based on the symptoms. (The use of medication should be under the guidance of a doctor.)
