Thanks again for the replies! It makes sense that the supplement would affect the test results. I shouldn't have taken it yet, but I was desperately trying to rid myself of this annoyance. I'm relieved it isn't related to diabetes because maybe this wont be permanent.

My thyroid was checked and it is normal. I have not had any surgeries or taken any antibiotics in a few years. The only trauma I could think of would be my poor posture and the way I sit at my desk. I've sat this way for years. I'm 6 feet tall, so I always lean forward and cram my toes into the floor. Could this repetitive action be the culprit? I haven't done it since my feet went numb. I actually haven't even sat at my desk since my feet went numb because I can't stand the feeling of my feet sitting flat on the floor, tingling away. I spend most of my time now either walking around or on the couch with my feet elevated.

This is truly the most annoying thing ever and I hope to get to the bottom of it. Thank you for all the information so far!!
