Hi. I've been hypothyroid for 5+ years on 75mg of thyroxine. I thought it had gone down but Blood tests are coming back normal. I'm waiting for total thyroidectomy as I have nodules on both sides. There is a +40week waiting list in East Sussex for any thyroid operations. Out of the blue I have developed high blood pressure. Neck is so tender but doc says it's blood pressure and not related to thyroid. Never had high blood pressure before. Going back to doc on Monday to start blood pressure meds. I'm not convinced but anyone experienced same thing? Or is it a vitamin deficiency?
