How to use phototherapy??

In 2011 I was covered almost entirely from my neck to my ankles with plaque psoriasis (although the plaques were joined together so it was difficult to tell it was plaque psoriasis!). Methotrexate didn't help at all, and Ciclosporin only had a very limited effect. In 2012-13 I had 12 weeks of UVB phototherapy (continuing to take Ciclosporin) and it cleared me entirely. I was left with very pale skin where my psoriasis was, but I didn't care about that, and it got back to it's normal colour eventually anyway. Over the next four years, I largely remained clear with only a very small number of patches coming back which could be controlled using steroid and vitamin-D analog creams. In June this year, it spread like crazy and once again I'm covered almost entirely from neck to ankles. After 3 weeks of UVB phototherapy, I let me consultant know that my psoriasis felt like it was burned and continued to be sore and itchy (which is odd because I didn't encounter any problems during my first course in 2012-13). He stopped my treatment and referred be for biologic treatment starting at the end of January 2018. I hope this info is useful, but let me know if you have any questions.

Thank you for your reply. This has been really useful. Hope your psoriaisis can be cleared using the Biologic treatment. Good luck to the future.
