Humira not working

Hi I started Humira in December and although I noticed some fading after about a month, my P has come back quite badly with new patches forming. Also the itching is terrible. I've contacted the hospital and have been given an appointment next week as I'm quite worried about it. Has anyone else experienced this or is it just that I will have to give the treatment more time to work. Previous to this I was on cyclosporine but it stopped working.
