Hi, I was diagnosed as hyperthyroid in the middle of May this year and was instantly put on propranolol which has helped a lot with my full body tremors and can now speak without my voice shaking and body rattling. My Gp got in contact with endo who advised I start on 20mg of carbomazle which I've been on now for about 6 weeks and can't see much difference. I was reasonably fit before this and now I can bearly walk with being so out of breath, is this normal? I've also got a huge lump on my throat (goitre.) which I'm getting a scan on this week - how does this get treated.? I also have my first endo appointment in 2 weeks, can you tell me what to expect please? Apparently my bloods showed I am borderline toxic???
