Can anyone please give me some advice on my latest bloods?
I had my thyroid completely removed about 15 years ago and have been on 125 thyroxine daily for a good number of years. Currently going through waves of fatigue. Some days I am ok, other days just seem to have no energy. I also take methotrexate for rheumatoid arthritis, and folic acid. Other than that, just cod liver oil.
