Hi I have Graves' disease, diagnosed 2 years ago and now med free for 3 months. Latest bloods serum TSH 1.49 mu/L range (0.20 - 4.50); serum free T4 14.3 pmol/L (7.0 - 17.0). 12 months ago I had what I thought was a reaction to reducing my Carbimazole- trembling, generally feeling nauseous but my thyroid levels were within range and my kidney markers dropped below the range to GFR 59ml/min/1.73m2 (60-160); then one month later dropped to GFR 47. As I was taking vitamin B complex and selenium amongst other supplements the nephrologist put it down to that and gave me a small course of steroids which bought the range back to GFR 61 and since then it has been steady at the same rate.
Last weekend I had a similar flare up but had palpitations, have been having pains in my toes and occasionally in my knees and tight hamstrings for weeks. I had my bloods done on Friday with the results shown.above but with a GFR of 57 but thyroid bloods still in euthyroid range!! Could this be something else other than Graves - I'm concerned I might have lupus!!
Any help would be appreciated.
