I have had Psoratic R.A. For 4 yrs. very painful indeed . 6 months ago I decided to give up coffee ----my Psorisis is so much better .Two months ago I bought a book ' eat to beat Arthritis ' by Margaret Patten and Jeannette Ewin.
I have given up wheat and all citrus fruits which has enabled me to really reduce my tablets .i also bought a magnetic braclett last November about £40 this too has helped to reduce the pain .
Well worth a read . Do hope this helps someone.
