Dr. Alon Seifan answered

Specializes in Neurology

Carpel tunnel: This is a common cause of numbness in the thumb. If it is just the medial aspect, this is more suspicious of medial nerve involvement (which is commonly caused by carpel tunnel) because the radial nerve innervates the lateral aspect of the thumb.

Dr Machanic and another doctor agreed
