If it is elbow problems and trapped nerve issues that is very different from diabetic neuropathy - as
@Cal M explains v well.
I had numbness and pins and needles in left little/ring fingers a while back. Got v worried about neuropathy and consulted Dr Google (who was excellent on the subject). Took myself off to a chiropractor who found a trapped nerve. But not in elbow. Mine was in shoulder half way between neck and shoulder joint. The wonderful man gave me a single treatment and advised me on some 'nerve pulling' exercises (lots of vids on you tube), and the problem disappeared within a day or two.
Comes back occasionally, and every time I realise that I am carrying tension in my shoulders, so I focus on posture and those exercises for a few days, and everything resolves. I have lower back issues, and tend to get tension in neck/shoulder as a result. I find it incredible that my lower back problem ends up with pins and needles in my left hand, but there you go, it does.
Not that I am saying that this will work for you, just that there are different things that may cause issues, and that there are more ways to skin a cat...
