basically i have a touch of psoriasis on my legs which comes out when im stressed and tonight i noticed a small patch about the size of a 5p piece on my forearm and im a bit worried incase its getting worse. i can cope with it on my legs cos i can cover it but my arm is a bit harder to hide. does anyone have any good tips on reducing the redness? its not itchy so i havent been scratching it and i have used eurax a couple times but dont know if this will do it any good or not. also i would prefer something i could buy over the counter as its a pain for me to get to the docs.
