Last time my thyroid was done about five months ago my TSH was suppressed and my FT4 was as usual at the lower end of normal range. So nothing is shouting out to persuade my GPs to run further tests.

They say I won't be allowed to try Imuran until I'm fully recovered from my lung infection. I just wondered how I will know if I'm recovered when the aches and stiffness are starting to increase but I still feel completely wiped out. I will ask on Wednesday about getting my cortisol levels checked but again, I don't think this is a test they routinely run. Thanks for your help.
