Pain in the left arm from shoulder to elbow

We talk about pain in the left arm, but there is no single type of pain. Depending on when it appears, how it does it and what sensations accompany us, we can rule out some conditions and incline them to others. For example, when pain in the left arm runs from shoulder to elbow, it may be one of the following injuries:

Carpal tunnel syndrome

In this particular case, the pain in the left arm from shoulder to elbow can also radiate to the forearm and hands. It is a syndrome that until now was almost specific to athletes such as climbers or tennis players, but due to the use of smartphones, computer mice and smartphones, it has become more common in the rest of the population. The carpal tunnel is located in the hand, in an area where arteries, veins, tendons, nerves, and muscles meet. If it is compressed, it will cause symptoms such as pain, weakness, and tingling, which can be spread throughout the arm by compressed nerves.

Tendinitis and bursitis

Although they can occur at the same time and are two very similar injuries, tendonitis and bursitis are not the same. Tendinitis is inflammation of a tendon, in this case the shoulder, which causes pain that runs down the entire arm. On the other hand, the bursa is a kind of bag in which there is synovial fluid and that serves as a protection between the bone and the muscle. If it becomes inflamed, it also ends up causing pain in the left arm from shoulder to elbow.

This injury affects the nerve network, something that causes your pain to manifest from the spine to the hand, through the shoulder and the arm. This injury occurs due to a stretching or compression of the nerves and, in the worst cases, they can separate from the spinal cord, causing the arm to be paralyzed. This type of injury occurs, basically, practicing some contact sport or as a result of car accidents.

Arm and shoulder pain when sleeping

There is a lesion known as cervicobrachialgia that is actually in the cervical, however, its pain radiates throughout the arm. Cervical and neck problems will affect the roots of different nerves that pass through the arm, and this compression will cause pain in the left arm and shoulder when sleeping .
