I've been told that my thyroxine levels are high and I need to be checked in 6 weeks to see f they are still high/to see if I have hyperthyroidism due to my immune system. If after the 6 weeks my levels are back to normal and I don't have overactive
thyroid I was wondering what might have caused the temporary spike in thyroxine? (Background info, I have crohns and rheumatoid arthritis and suffer from anxiety and stress)
