Re: numbness in pinky and ring finger
Probably there is an impingement of your ulnar nerve. That can be caused by several reasons, so you should start with having a neurologist consultation. I have ulnar nerve damage due to cervical compression in my spinal cord, but it will take some diagnostic tests to determine the cause for you. I am a musician also, and I understand your concern. I have regained a lot of my function in my fingers after surgery and physical therapy. I still have some tingling and numbness though.
