[41M] Experiencing numbness and mild weakness in left hand and forearm

What might be happening

Based on the information provided, possible explanations for your symptoms include:

• Cubital Tunnel Syndrome: This condition is caused by increased pressure on the ulnar nerve, which passes close to the skin's surface in the area of the elbow commonly known as the "funny bone." You might feel like your fingers are "falling asleep." Numbness and tingling in the ring finger and little finger are common symptoms of cubital tunnel syndrome.

  • Treatment typically involves avoiding activities that cause symptoms, wearing a splint or supportive brace, and in some cases, surgery.

• Ulnar Nerve Entrapment: This occurs when the ulnar nerve in the arm becomes compressed or irritated. The ulnar nerve is one of the three main nerves in your arm and it travels from your neck down into your hand. This can give you symptoms along the way, such as numbness, tingling, or weakness in the hand, ring finger, and little finger.

  • Treatment usually involves physical therapy, medication to relieve symptoms, and in some cases, surgery.

• Peripheral Neuropathy: This results from damage to your peripheral nerves and causes weakness, numbness, and pain, usually in your hands and feet. It can also affect other areas of your body.

  • Treatment typically involves managing the condition causing your neuropathy, relieving symptoms, and improving physical function.

What you can do

1. Avoid activities that require you to keep your arm bent for long periods.
2. When you use a phone, try to use it on the side that's not causing symptoms.
3. Try not to lean on your elbow or put pressure on the inside of your arm.
4. If your symptoms are severe or persistent, seek medical attention.

What you should look out for

If you notice any of the following, you should seek immediate medical attention:

• Sudden onset of severe pain
• Loss of sensation or movement in your arm
• Signs of a stroke, such as facial drooping, difficulty speaking, or a sudden severe headache
