I was diagnosed in Jan and am now on 75mg thyroxine. I feel so bad. My whole life has changed. I asked my doc if mysymptoms are normal or could they be side effects of meds. She said they are not and there must be something else wrong with me?My chest feels painful, sort of sore like I have over exercised. I sweat all night. I feel shaky and I tremble. I have a bad headache ever day and I am exhausted. My scalp feels sore too to touch. I have to wait another 4 weeks for next blood test before meds can increase. Not sure I can wait and finding it hard to manage at work now. Are these symptoms normal? I have no confidence in my GP in this regard and feel she is guessing? Any advice welcome.
