Arm pain is not a disease in itself, but a symptom that can be due to various diseases and injuries in the area of ​​bones and joints as well as muscles and tendons.

Pain in the left arm does not necessarily mean a person is experiencing a heart attack. The best thing to do is not to jump to conclusions, there are numerous reasons a person can have pain in the left arm. Although it may be bad at times, it is often caused by an underlying symptom of something else.

While a heart attack is possible and associated with left arm pain, regular or chronic pain in the arm is an indication that something else is wrong. Most arm pain is a result of an injury radiating from somewhere else in the body. The following is a brief summary of the leading causes of pain in the left arm:


Carpal tunnel syndrome

This is a progressive condition that can cause severe discomfort in the arm. This condition is due to a pinched nerve in the wrist and is often caused by repetitive motion of the wrist or arm.

An inflammation or irritation involving the tendons can lead to tenderness surrounding the joint. This is very common in the shoulders, elbows, heels, and wrists.

Sprains or breaks are usually caused by an injury or fall, and often times are not noticeable at first. A hairline fracture or simple sprain can cause discomfort without being obvious.

    I have this type of dull ache between my left shoulder and elbow, Elbow never hurts. But I have had bursitis in shoulder from time to time. Had a miniscus tear in shoulder, no surgery, only the wire thing stuck in and he also tried to clean some of the upper arm area. said I had a lot of arthritis on bone. This was about 8 years ago. At that time I did not have this arm/bone pain. Some days the ache is worse than other days. Is there any exercise that can help this?

      Hi holly, exercises for this type of injury could be limitless due to no contractile tissue (muscles) being injured. I would recommend resistance band activities which involve shoulder rotation to reduce the chances of weakened muscles.
