Is Sleeping Position Causing Numbness in My Pinky Fingers? - Neurosurgery

More Info

The numbness you are experiencing in your pinky fingers during sleep could indeed be related to your sleeping position. When you lie on your back with your arms positioned under your abdomen, it can lead to compression of the nerves that innervate your hands and fingers. Specifically, the ulnar nerve, which runs along the inner side of your arm and into your hand, is responsible for sensation and movement in the pinky finger and half of the ring finger. If this nerve is compressed, it can lead to symptoms such as numbness, tingling, or weakness in those fingers.

When you sleep in a position that puts pressure on your arms or hands, it can restrict blood flow and compress nerves. This is particularly true if you are lying on a hard surface like a carpet, which may not provide adequate support for your arms. The ulnar nerve can be compressed at several points along its path, including at the elbow (cubital tunnel syndrome) or at the wrist (Guyon's canal syndrome). However, in your case, it seems more likely that the position of your arms while sleeping is causing temporary compression of the nerve.

It is also worth noting that the position of your arms can lead to a condition known as "Saturday Night Palsy," where prolonged pressure on the radial nerve (which runs along the outer side of the arm) can cause weakness or numbness in the hand. However, since you are specifically experiencing numbness in your pinky fingers, the ulnar nerve is the more likely culprit.

To alleviate these symptoms, consider adjusting your sleeping position. Here are some suggestions:
1. Change Arm Position: Instead of placing your arms under your abdomen, try resting them alongside your body or on a pillow. This can help reduce pressure on the nerves.

2. Use Supportive Bedding: Ensure that your mattress and pillows provide adequate support. A mattress that is too firm or too soft can exacerbate pressure points.

3. Take Breaks: If you find yourself in a position that causes numbness, try to change positions or take breaks to relieve pressure on your arms.

4. Stretch and Strengthen: Incorporating stretches and strengthening exercises for your arms and hands can help improve circulation and nerve function.

5. Consult a Specialist: If the numbness persists or worsens, it may be beneficial to consult a healthcare professional, such as a neurologist or a physical therapist. They can perform a thorough evaluation, including nerve conduction studies, to determine if there is an underlying condition contributing to your symptoms.

In summary, your sleeping position is likely contributing to the numbness in your pinky fingers. By making some adjustments to how you sleep and being mindful of your arm positions, you can help alleviate these symptoms. If the problem continues, seeking professional medical advice would be a prudent step to ensure there are no underlying issues that need to be addressed.
