[|Human|] I have nail psoriasis on both thumbs and nowhere else.  I have been to 4 different doctors and tried several different topicals over the past year.  Sometimes I see some improvement but then it gets worse again.  Then I took a 2 week vacation and spent a lot of time in the sun.  When I got home the skin had become smooth and the nails had begun to grow normally.  I have read about light therapy and Xtrac laser, but my doctors seem hesitant to go there.  He wants me to try Ultravate, but it seems topicals dont work cause I wash my hands frequently.  What can you recommend?
[|AI|]  Hello, Welcoem to the forum, and thanks for choosing the forum. After reading your query I can make out that you are quite stressed with nail psoriasis. If I were your treating dermatologist then would have given you Ultraviolet light therapy with Narrow band UV B. It is the safest modality and can be taken without any side effects. I suggest you to meet your dermatologist and take guidance for certain hand held devices which can be used at home. Certain medical therapies including methotrexate can be used under strict dermatological guidance. All the best.
