The causes of tendon pain when exerting the arm may be transient strain injury, ligament strain and tenosynovitis.
1. Transient strain injury: If the arm has recently been subjected to high-intensity exercise resulting in transient strain injury, the muscles, tendons, ligaments and other tissues of the arm spasm, and when the arm is exerted, the tendon will feel pain.
2. Ligament strain: intense external force and incorrect posture and other reasons can cause arm ligament strain, which will cause the arm to feel tendon pain when exertion.
3. Tendovaginitis: after suffering from tendovaginitis, when the arm exerts force, it will make the joints move, which can lead to friction between the tendon and the tendon sheath, and when the tendon sheath with inflammation is rubbed, it can feel pain.
If you feel tendon pain when you exert your arm, you should go to the hospital to find out the cause and actively cooperate with the treatment.
