Hi Clare

I have MS, and my sister has Lupus - and yes, autoimmune diseases can cause crazy things to happen to your body, and you can have more tha one of them. I know of at least two people who have both MS and SLE, and I have MS and ITP (autoimmune blood disorder) - having said that, I am sure there could be many things that could be causing your problem (although I am not a doctor - so can't suggest anything specific).

I think the idea of filming your issue is a terrific one (thanks Sleeper). because most of what we go through is 'invisible' to others, Medical staff are often sceptical, because it is not obvious.

Good luck finding your answer, I think your first step would be to try and arrange an MRI. That will give you a much better idea of what may or may not be.

Regards
