I am taking meds for hyperthyroid and RA. My immune system is totally up the wall, but have found if I have a virus or infection my RA goes into overdrive, and am unable to function even with the limited mobility I normally have. If I go to bed - only place I can get warm I am in even more pain than normal when I try to move. And is anyone else totally fed up of people telling you - Its the weather making your RA worse - I WISH!!!
