Very sensitive side fingertip pain
It’s been around 5 days on the side of my fingertip having a very sensitive and sharp pain upon contact or even stretching my finger out. It’s also somewhat stiff but I can knock on wood and wiggle it with no pain, but upon contact on my fingertip it lets out a sharp shooting pain, and brushing anything against it even as soft as a blanket causes me pain. I tried ibuprofen, Tylenol, and ice but I didn’t notice a difference. I did go to the doctor but he said he didn’t know what this was, he assumed it could be a popped blood vessel, nerve damage, low vitamin D which I’ve had trouble with in the past or something called paresthesia.
Anyways I’m curious if anyone knows what this is or the cause preferably so I can treat it more properly. Side note he gave me steroid cream but I still haven’t noticed a difference.
