What Causes Upper Arm Pain? 14 Causes To Consider

Tendinitis

Tendinitis is known as inflammation of the tough fibrous cords that connect muscle to bone. The tendons that connect muscles to bones are crucial for movement. Tendon tears may result from chronic tendon irritation. The area immediately around a joint becomes sensitive and painful. This may damage a tendon’s mobility and create joint discomfort.

Any tendon vulnerable to tendinitis, such as the elbows, knees, shoulders, heels, and wrists. Although tendinitis may occur everywhere in the body, it most often affects a specific group of tendons, such as the triceps tendon, rotator cuff, Achilles tendon, and carpal tunnel. Tendon injuries may be either abrupt or sudden such as those from a sports injury, or slow and long-term, such as tendonitis from overuse or repetition. It may cause weakness around the afflicted region, reduced range of motion, and discomfort and tenderness in the damaged tendon. 

Bicep tendonitis occurs when the tendons that connect the biceps muscle at the front of the arm to the shoulder and elbow become inflamed. Overusing the upper arm muscles leads to bicep tendonitis due to repetitive motion. Mild tendon injuries are easily treated, and full recovery occurs within two to three weeks. Rest and pain medication are effective treatments for tendinitis. However, depending on its severity, repairing a damaged tendon may require surgical intervention.
