I was diagnosed with an overactive thyroid...it was causing tiredness, weightloss, etc. I was given carbizomole tablets, which within 4 days had caused me to because massively underactive. I was advised to stop these tablets and go onto thyroxine. After a couple of weeks this has caused me to become overactive again. The doctors are telling me to leave it and it will go back to normal...i do not understand how they know this as I am getting all the symptoms i previously had when overactive. Another problem i have is severe pain down my legs that can either cause me to vomit or cry...i can bear it most of the time, but 2 doctors are saying it is associated with my thyroid but 2 doctors say it is not. I just want to get these problems resolved, but i am confused. Could you help me, please?
