"I'm a little but worried because I seem to also be suffering from reduced manual dexterity: I'm frequently dropping things with my right hand, drop bottle caps while trying to open, fumble with different coins from my change purse, etc. I'm seeing a neuro but these are some recent developments which I have yet to report.

Hi dolby,
What kind of work do you do?
This sounds so much like how my RSI started.
I'm wondering if it is some kind of repetitive strain injury?

You might want read on our Thoracic Outlet Syndrome forum about it & RSI, just to see if anything fits for you. Be sure to check out the sticky threads too.

I wrapped kitchen towels around my elbows to help me keep my arms straight and the padding helped reduce the pressure from the mattress.
I had the neoprene wrist wraps that were soft but supportive and warming.
