Causes of muscle pain under the thumb

Pain in the muscles under the thumb can be harmful to the health of the thumb and the body, and will also affect normal life. Therefore, many patients with pain in the muscles under the thumb want to fully understand the causes. The following content provides a detailed introduction, and you can take a comprehensive look at the causes below.

Causes

There are two tendons at the base of our thumb, one is the abductor pollicis longus and the other is the extensor pollicis brevis. When you raise your thumb, you can feel these two tendons at the base of your thumb at the wrist. Tendons are like flies; the contraction of the muscles pulls the tendons and drives the movement of the fingers. If these two tendons are moved too frequently, or are used with excessive force or incorrect posture, the tendons will be injured, causing inflammation of the surrounding bursa, resulting in pain in the wrist on the thumb side, affecting the movement and pain of the wrist and thumb.

diagnosis

The location of the mother's wrist pain is near the thumb and wrist. Symptoms usually worsen slowly rather than occurring suddenly. In severe cases, they will not only hinder wrist movement but also affect sleep. Patients will feel joint stiffness and even neuralgia-like pain that spreads up the arm and down to the end of the thumb. The pain is often exacerbated by grasping the hand, lifting the thumb, or bending the wrist toward the pinky. You can see a little edema at the styloid process at the end of the radius at the wrist, which is painful when pressed.

Identification

Wrist pain on the thumb side should be differentiated from carpal tunnel syndrome, carpal osteoarthritis, radial neuralgia, tendon infection, etc.

Do the Finkles test, which is to hold your thumb and bend your wrist toward your little finger. If the inflamed tendon bursa is pulled and causes pain, you may have mommy wrist!

Clinically, the above examinations can be used to make a diagnosis, but for some atypical cases, "skeletal muscle ultrasound" can currently be used for diagnosis. The advantages of ultrasonic examination are accuracy, time saving, and no radiation hazards.
