I've taken myself off Levothyroxine because of the horrendous joint pain and leg cramps I've been enduring for the last couple of years. I've been off it now for 2 weeks and the joint pain has virtually gone, as have the cramps. I was taking 100mcg levo with 40 T3 prescribed by my GP - I had total thyroidectomy 30 years ago. The problem is that my hypo symptoms are returning with a vengeance - extreme tiredness, freezing cold, brain fog, vision problems etc etc. What to do? I can't take levo because of the pain in my knees - some days I can't walk because of it and the leg cramps are agony. My GP refuses to prescribe a higher dose of T3 (because of cost!) and doesn't believe the side effects of levo I am experiencing. Does anyone think NDT would be beneficial and, if so, where could I obtain some without prescription - my GP has never heard of NDT! Any help very gratefully received.
