What could be causing pain in my left shoulder and arm?

Pain in the left shoulder and arm can arise from different causes. According to the studies provided, common reasons include injuries to the muscles or tendons, inflammation, or issues with the nerves.

Possible Causes:

1. Injuries:

• Injuries like sprains or strains can affect the shoulder and arm.
• Overuse or sudden movements may lead to these injuries.

2. Inflammation:

• Conditions like bursitis or tendinitis involve inflammation of the shoulder components.
• These conditions can cause persistent pain and discomfort.

3. Nerve Problems:

• Nerve compression or irritation can lead to pain radiating from the shoulder to the arm.
• This can be due to conditions like a pinched nerve.

What to Do:

It's important to see a healthcare provider to determine the exact cause of the pain. They can perform an evaluation and recommend appropriate treatment. Depending on the cause, treatments may include rest, physical therapy, or medication to reduce inflammation and pain. Please note that if the pain does not change depending on movement of the shoulder or neck, or if you have personal or strong family history of heart disease, you should seek immediate medical attention as left sided shoulder pain can sometimes indicate an emergent heart condition requiring treatment.
