What Causes Arm Weakness?
- The blockage or rupture of a brain artery causes serious symptoms that must be treated immediately. The blockage can be temporary or transitory and go away on its own after a few hours or minutes. However, it must be treated immediately, as it is a serious sign.
- An arm injury, sudden or over time, can lead to weakness.
- Direct trauma from a fall or accident can cause localised damage to the nerves or muscles in the arm.
- An overuse injury, also known as a repetitive stress injury (RSI), can become permanent if left untreated. It is caused by long-term damage to the nerves, muscles, and tendons in the arm or shoulder from prolonged periods of exercising the arm with the same movement.
- Simple fatigue from unaccustomed exercise can also cause RSI.
- Arm weakness refers to the loss of strength in the arm and the inability to move an arm due to decreased muscle strength. Overusing the affected arm can cause pain, protection, and subjective weakness.
- Nerve or disc damage can cause pain in the upper back and neck. The arm may appear weak because you are trying not to use it, or it is "protecting" it.
- A rupture or other damage to a cervical disc causes pain when the fluid between the bones of the spine for cushioning is lost. Wear and tear of bones and cartilage occurs due to normal aging.
- Crowding of the nerve roots in the neck can cause pain and weakness in the arm.
- Arthritis in the spine can cause bone spurs that pinch on nerves.
- Narrowing of the spinal cord can cause pressure on the spinal cord.
- Thyroid disorders also raise the risk, for reasons that are not completely apparent, of carpal tunnel syndrome.

To treat it, the doctor would first need to diagnose the root cause of the discomfort. They will first take a history and physical exam, asking about your activity, possible injuries, and symptoms.
Based on your symptoms, the following tests can help your doctor make a diagnosis:
- They may ask you to raise your arms or make other simple movements to assess your range of motion. This can help them identify the location and cause of possible injury or pain.
- Blood testing can help the doctor diagnose certain diseases, such as asthma, that can cause arm pain or conditions that cause joint inflammation.
- Your doctor will detect broken or cracked bones by taking X-rays.
- If your doctor thinks your arm pain is associated with possible heart complications, they may order tests to assess how well your heart is working and to assess the blood flow through your heart.
- Ultrasounds use high-frequency sound waves to take pictures of the inside of the body. They can help your doctor find joint, ligament, and tendon problems.
- Your doctor may order MRIs and CT scans to obtain a more detailed image of your soft tissues and bones, which can help them spot problems.
