Hi there, 6 weeks ago I got diagnosed with over active thyroid. I saw an Endo on Friday and I told her that at the same time as my thyroid symptoms started I also got pins and needles in mainly my right arm but occasionally on my feet. She has told me that the pins and needles are nothing to do with my thyroid. I have my B12 blood test of which I am 383 which is within the normal range. I will go and see my gp next week but has anyone else had the same?
