Upper arm muscle pain refers to the pain in the muscles between the shoulder and the elbow. The pain may range from slight, mild to severe. Treatment also vary from ice compress to medications and physical therapies. In some cases, it could be a sign of heart attack. In the first place, we should figure out the reason of this painful upper arm muscle discomfort.
Here are the possible reasons of upper arm muscle pain:
1. Injury
If there is an injury, such as a sprain or a fracture in your upper arm, naturally you will feel pain. You may not feel the pain immediately after getting the injury. But you can feel it gradually as you move your arm.

2. Muscle Fatigue or Tension
Muscle overuse can be the most likely cause of upper arm muscle pain. If so, just get enough rest and try some ice compresses.

3. Pinched Nerve
This is another common reason of arm pain. If your nerve is twisted, stretched, or pinched, call your doctor as soon as possible.
4. Bursitis
Bursitis means there is an inflammation of the bursa. It could be a deep aching pain that goes worse as you move your shoulder or arm. You may need some anti-inflammatory medications, or physical therapy, to treat your red and swollen arm.

5. Sign of Heart Attack
Upper arm muscle pain can even be a sign of heart attack if the pain is sudden and sharp. Also, someone consider it as dull and aching. The pain here is unexplained, not resulting from any injury or overexertion. It may also come with chest pain, shortness of breath and nausea. If this happens, don’t hesitate to ask for your doctor’s help before an impending heart attack strikes you down.
6. Bicipital Tendinitis
Too much exercise can also cause upper arm pain, which generally result from a tendon torn, especially in the biceps muscle. If it is mild, have a rest. Ice packs, anti-inflammatory drugs, and physical therapy can be possible solutions. If the pain doesn’t disappear two months later, consult an orthopedic doctor.
7. Cervical Disc Herniation
Upper arm pain sometimes can be a hint of the cervical disc herniation.You can try traction, exercises, and massage in coping with this condition.

8. Fibromyalgia
If the pain is unexplained, you can’t describe its intensity and only feel the fatigue it brings, then it may be the fibromyalgia. This happens more often to women.
