Once in a while after I wake up I get a strange numbness/tingle in my fingers/hand/wrist. Today it is kind of annoying as it has been there for about 3 hours now on my right hand's thumb, forefinger and middle finger after sleeping on my right side. Everything works as it should but the sensation is annoying. In the past I have had either hand start to go 'asleep' also, depending on how I was laying, usually with my arm above my head, so I moved my arm elsewhere. The problems only occur when I am laying down/sleeping. I dont remember this happening before my accident. My theory so far is that this might have something to do with the rods in my back going up to T2 not letting my back flex and causing additional pressure on my shoulders, pinching a nerve somewhere in my arms causing this, but would like to get other opinions regarding this. Where do the nerves that go to your hands travel down the arms? Any ideas on how to stop this from occuring?
