Does this sound like circulation problem?

My hands have been getting tingly, especially the left one. Also my arm will ache, my feet tingle sometimes when I sit or stand a long time. I feel cold even when the room is warm. My back hurts in one spot in the middle of my back and no drs have been able to tell me why.

I've been going to the Mayo Clinic and have several tests done for pain in my chest. They've been checking my espohogis (sp?). I'm also going for an MRI on my head and neck because I keep getting a pain in my head. Does the tingling and cold feeling sound like circulation or nerve related? I'm wondering if my next step would be a heart dr? I've had ekg's and stress test a few times in the last couple of years and they say my heart is fine, but I've never had an echo or had my arteries checked.

Yesterday I was doing some stretches and was using the exercise bike. After I got done I felt light headed and tingly all over.



One other thing I get is itchy all over - especially the back of my neck, my elbows, knees, feet and my back where the pain is. No rash, just itchy.
