Pain at the base of the thumb may be related to trauma, tendinitis, arthritis, and other conditions.
Traumatic injury to the thumb may cause pain and limitation of movement when the joint capsule, tendons and ligaments are strained.
The thumb has the highest degree of involvement in hand activities, and repeated friction between the tendon and the tendon sheath over a long period of time can lead to the formation of stenosing tenosynovitis, which can cause pain at the root of the thumb, and in severe cases, it can lead to ringing fingers and limited flexion and extension activities.
Rheumatoid rheumatoid arthritis, gouty arthritis involving the metacarpophalangeal joint will cause destruction of articular cartilage, which will also cause pain at the root of the thumb.
When making a fist for a long time, fatigue of the muscles and ligaments of the thumb can also cause pain, which can be relieved after rest.
If the symptoms of pain at the base of the thumb, it is recommended that the patient go to the hospital for medical treatment to determine the cause of the disease and carry out regular treatment.
