Thanks for your replies.

I'm not diagnosed yet. Dr's appointment is on Friday. I'll be questioning him then, thoroughly, as to what the condition is exactly. The pinky's seem to be fine but the other fingers are all tingling.

Last night when I eventually went back to bed I found that each side I slept on was affected so I would have to shake arms/wriggle fingers etc until it subsided and try the other side for a time. Being pregnant I have to sleep on a side but either way I go it hurts after a while and I am not sleeping on my arms or hands. I just hope this is a temporary issue related to fluid retention and nothing more serious. My ankles incidently are not swollen so the fluid is only in the hands/fingers and it is only at night while I'm in bed that the cycle starts over again.
