I have been suffering from pins and needles sensations throughout my body for the last couple of months, and I have no idea what is causing it. Some tests that I have run are my B12 levels (normal) std panel (normal so far) and my thyroid. The only issue with my thyroid was that the level was off the very first time I tested it but then went back to normal the second time. Anyone have any ideas of what might be going on?
