Introduction
Shoulder tenosynovitis commonly occurs at the top of the shoulder joint, particularly affecting the long head of the biceps tendon. This condition arises from repeated friction between the tendon and the tendon sheath without adequate rest, leading to irritation of the sheath. It primarily causes pain in the anterior shoulder or along the biceps muscle, with symptoms often worsening at night. As the disease progresses, it may lead to restricted shoulder joint movement, joint stiffness, and limited range of motion.
Shoulder tenosynovitis commonly occurs at the top joint of the shoulder, particularly affecting the long head of the biceps tendon sheath.
This condition is usually caused by prolonged heavy physical labor or intense exercise, leading to repeated friction between the tendon and its sheath. Without adequate rest, the tendon sheath becomes irritated and inflamed. Additionally, factors such as exposure to cold and wind, or external trauma from impact, may also contribute. The main symptoms include pain in the front of the shoulder joint—specifically at the site where the deltoid muscle attaches or around the biceps muscle. The pain may be intermittent or persistent and often worsens at night. As the disease progresses, it may lead to restricted shoulder joint movement, joint stiffness, and a catching or snapping sensation.
After diagnosis of shoulder tenosynovitis, patients should ensure sufficient rest. Supporting the affected arm with the elbow flexed can help avoid severe pain caused by upper limb rotation. Symptoms may also be improved through treatments such as electrothermal therapy or massage, administered under the guidance of a qualified healthcare professional.
