Thanks kiwi, great sites. Will definitely help with what I need to ask, and I will get a list ready, including tests to ask for. So, myasthenia gravis does not cause an elevation in ANA titre? I was thinking all autoimmune diseases did. That's debunked my theory. I just read in the link you just posted that scleroderma causes muscle inflammation then weakness. It doesn't explain eye droop, heat intolerance etc. I would be pretty unlucky to have two serious and rare autoimmune diseases. I just have to be patient and wait for test results. I really have so many MG symptoms, but even if I test negative, the medication might give me a better life quality. I can only ask.
