Recent numbness in medial aspect and tip of right thumb. no known injury?
A doctor has provided 1 answer
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.
