I have now spoken to a rheumy nurse. She is not overly worried about my skin problems. Thinks 4 months is too early to judge whether I should stop the drug. She has advised either seeing my GP or sending photos. I shall speak to him first, probably tomorrow. The nurse thinks there may be other reasons for the problems. But unless it could be the combination of the two drugs (Methotrexate and Remsima) I can't think of what it could be. The GP doesn't prescribe these drugs so I don't really see that he will have great experience in the side effects.
Well, thanks for your help Gnarli and Knit17. I'll have to see how I get on with the GP.
