Question
I'm 66 years old.Since 2 years I'm experiencing biceps muscle loss.Consquently I'm losing function of both hands from elbow including fingers.Is it due to muscle loss or nerve loss or both?Is there any treatment and/or are there any medicines to treat this condition?  

Answer
K S,

You need to see a neurologist.   This may be from a severe problem in your neck that is encroaching your nerves or spinal cord.   It's not the muscle.   It's a nerve problem.   A cervical spine MRI will show the anatomy of this. That would be the first step.  A nerve conduction study will also prove if there is nerve damage (or muscle damage).   The neurologist is the doctor you need to see.

'Best,

Dr. G
