i'm going through the same thing now, been on mtx for 11 months, was clearing up but it started to come back with a vengeance in November. I went to see my derm yesterday and he has increased my dose to 17.5mg, i was on 15mg. He said i must be patient with mtx, it will get a lot better soon. It is just very frustrating as it was all going so well and now.....back to square one! I use dovobet along side my mtx, as well as the moisturisers and emollients, I hope your P starts getting better soon!
