What Causes Pins And Needles" Sensations In Hands And Arms Along With Nerve Pain In Lower Back?

I have been waking up with "pins and needles" sensations in my hands and arms for the last few months - never before. I have also been feeling carpal-tunnel-like sensations in my right forearm and had a ganglian cyst in my right wrist fo about a year last year, which went away after I got replaced my Blackberry with a Samsung touch phone (much less and slower emailing). I also have had nerve pain in my lower back since I was a kid (I am 50) and have had what feels like nerve pain issues in my irght calf and my hips (either that or arthritis) since I gave birth to my daughter at 41. I've mentioned the leg complaints to my doctor, who told me, after examining me, that I am healthy and i don't exercise enough. However, the hands falling asleep at night is a new symptom, and somewhat worrisome.
