Hi wonder if anyone could give me any advice please? I was diagnosed with Hashimotos 5 years ago. Prescribed levothyroxine just over 2 years ago, now on 75mcg. Been feeling dreadful for sometime, visiting surgery for help but won't prescribe more levo as my thyroid levels are on baseline of normal although I have had a referral for an endo which is not until October. I have experienced chest pain and palpitations plus shortness of breath for months. GP recently sent me for a 24 hr ECG this showed ST depressions suggesting I have cardiac ischima. I think this problem may be to do with my Hashimotos?
