What causes a hard lump on the finger joint?
Disease description:
Recently, I've been quite busy with work. I noticed some mild pain in my fingers while working but didn't pay much attention. When I got home at night, I saw a hard lump had developed on the joint of my hand. I'd like to ask, what could cause a hard lump to appear on a finger joint?

It is usually caused by strain, allergies, or similar reasons. Ganglion cysts are a common cause of hard lumps around joints and are associated with excessive overuse. When finger movement is significantly affected due to pressure from the cyst, surgical treatment may be necessary. The aforementioned conditions are typically benign tumors that grow slowly. If the above symptoms are accompanied by itching, it could be due to skin allergy. Allergies can not only cause itching but also lead to the development of firm nodules in various parts of the body.
