I'm so fed up on this new combo of T3 T4 everyday I wake hoping to see some improvement. Rotton tingling sensation in my arms and legs not as tired as I was last week small improvement palps gone and anxiety so I suppose somthing is working. It's just the heavy feeling in my body and lightheaded at times when will I start to feel the benefit of the new meds or am I just one of the people who can't take T3. Why was I put on this when my T3 was never tested. I only found out about all the proper tests I should have had done when I joined this brilliant site after being put on new combo. Its a bank hol here in Ireland this mon so first thing Tuesday morning I'm ringing a private endo in dublin heard good things about her going to get tested for adrenaline all vitimins and hashimotos. I can't believe how neglected doctors are with their patients. I'm diagnosed over 10 years with underactive thyroid due to all the radiation and chemo I was on when I had cancer in my. 20's but looking back I was never tested right they always just tested my t4 and TSH. I'm 50 now so god knows what damage has been done. Sorry for the moan but without all of you on this site I'd have gone mad the past few weeks. What a brilliant support site thanks so much.
