Well 2 weeks ago my foot started feeling so cold they could shatter!!It made them feel as if they were burning. It is from my foot to my butt and the pain is so bad! I have now had nerve blocks which didn;t work and trigger point injections.Nothing is helping!! nothing.I know that this could be from my AVM growing or swelling> I have steel phenomana.(spelling)durrr…It could maybe P.a.d.?I had mri and now awaiting results…hmm sound familiar?!!
