Hi! This sounds exactly like what I’ve been going through. I had a right hemithyroidectomy for a benign nodule a year ago and have been extremely sick since. I found out at the time of surgery I have Hashimotos, though I previously didnmt have symptoms. My TSH went above 8 post surgery. I went on levothyroxine for a few weeks and became very ill, then went off meds and my TSH naturally lowered over time. It’s now at 3.5 and my Hashimotos antibodies have interestingly also lowered, but I feel unwell constantly. I’m dizzy, have internal tremors, exhausted, vertigo, nausea, weak and achey. My year has been a right off with intense and terrifying symptoms with heart rate increasing out of nowhere, temp dysregulation among other things . I have been in EE 8 times, and seen multiple specialists due to so many symptoms. Did you experience any side effects from the levothyroxine? I feel that endocrinologists have no idea about treating symptoms and only defer to numbers. I have been told my symptoms are ‘unusual’ and that I am a complex and mysterious case. I feel like no doctor will be able to help me.
