I have a multinodular goitre. Thyroid tests are generally 'normal' but two recent ones (and odd ones in the past) show lowish levels of TSH (around 0.1 with ref 0.35 - 6). A these times my fT4 can also drop a bit. I had fT3 tested last time and it was smack in the middle of the range.
I have been feeling grotty since December and I have two weird symptoms that I was wounding if anyone else has experienced.
I get a strange almost panic-like feeling in my chest, but I am not anxious. It makes me feel like I should be, if that makes any sense.... This has happened for a couple of years, and seems to parallel with the dropping TSH levels. For the past couple of months I have had a weird vibrating feeling in my body. It stopped for a couple of weeks but is back again today. When I woke up this morning my insides were vibrating and when I looked at the wall it was 'moving' very slightly back and forth in time to the vibrations inside me. At its peak in the last cycle of this, I searched for my mobile in my pocket when I was sitting in the car. I thought that it was vibrating - it wasn't. The vibrations aren't always this strong, but still very distracting.
So, I guess I am wondering if I can be suffering actual hyper symptoms when my fT4 is quite low (varies, can drop to 12 on a scale of 9 - 22, but more normally it is around 16) and my fT3 is mid-range.
So fed up being exhausted and not knowing what my 'problem' is.
