i got this confused all the time, and my pcp finally set me straight on the numbness issue - that is always your nerves. if you have curculation problems, you wouldn't have numbness! who knew?
it is possible you have both problems (not trying to say that you don't), but poor circulation apparently makes you feel pain or pressure (or something like that), whereas the nerves are causing numbness.
but, as you well know by now, i've had some really strange and bizarre problems and solutions!!!!
