Tendonitis nodosa is a hard and painful nodule formed by exudation or hyperplasia caused by aseptic inflammation of the tendon, which will affect normal life and can be relieved by medication and surgery. Tenosynovitis nodules are caused by long-term friction of the tendon in the tendon sheath, resulting in aseptic inflammation of the tendon and the tendon sheath, aseptic inflammation will lead to an increase in localized fluid to form a lump, and long-term injuries will lead to self-repairing hyperplasia of the tendon and the tendon sheath to form a hard nodule. Generally, the nodule will seriously affect the normal life, resulting in local activity obstacles, you can rest, reduce the local movement to improve the symptoms, you can also use some anti-inflammatory drugs under the guidance of the doctor, such as celecoxib, and so on, and in severe cases, need to carry out surgical treatment. Acute tenosynovitis progresses quickly, patients need to immediately consult a doctor, follow the doctor’s instructions, under the guidance of the doctor for standardized treatment, to avoid the deterioration of the situation, affecting normal life.
