This is all quite interesting - and disturbing - to read. The latter especially in your case, Paul.

I'm having another strange archipelago of symptoms/side effects... don't really know what to call them. Beginning about this past February my hands, specifically the thumb and first two fingers, went cold, numb and tingly. To make a long story short I've had the usual battery of tests - first those delightful nerve conduction studies that Paul speaks of, then an MRI of the cervical spine. Result: no nerve or spinal damage. For which of course I'm grateful.

Yet the problem persists. Most of the time if feels as if there are hundreds of tiny pinpricks in my hands and radiating up my arms, sometimes to the shoulders. The fingers are always cold, sort of the halfway feeling you get when you've come in from extreme cold and your hands are beginning to warm.

I should add that this isn't painful. But it's damn disturbing, and since both my neurologist and my regular MD have no answers for me, quite a puzzlement.

I am 3 1/2 years out from RT and I had no chemo but I did have a neck dissection. No idea what of any of this may have contributed to it. I also get lightheaded from time to time when I try to stand up. So maybe it's a circulation problem.

Sure is weird! Any thoughts appreciated.
