Hi, I'm Spastic Ada and I read your post. When I read it, I had a sense of de-ja-vu. I have Stills Disease and it is a very rare arthritis. The symptoms are joint and muscle pain, a salmony pink color rash that can be bumpy or flat, and daily spiking fevers. It is a very hard arthritis to dx because the RF and ANA are negative. On my profile I have pictures of what my rash associated with Stills looks like. You are welcome to take a look. It is very important to keep a daily journal of symptoms because it can help get it dx'd a lot sooner.
I hope you start feeling better soon.
Thanks for your great comments I've checked into your Stills Disease and it appears that 100% of sufferers have fevers - which I haven't had. I guess this is good news because I don't think I can have Stills Disease (although everything else rings true!), but the bad news is I now can't label it!. Thank you so much for your help though - I want to wish you all the best for the future :-) I've also taken your advice and have listed all my symptoms ready for the doctor when my blood results come back next week - because I know I'll forget them otherwise.
Take care, Nicola x
