psoriasis
"I have psorasis on and off for over 20 years.  It effected my ankles only with a small patch on elbows from time to time which has not come back for longest time. 
However the ankles would flair up so bad. Tried all the creams possible, Dovenex, Betnovate, mix by the pharmacist with tar in it .. and many more.  All of these worked for awhile. The I took tablets internally, Acretin, Fumaderm... did not work. Side effects such as hot flushes, aches and pain, headaches. 
Then got tested for Stelera.  Sceptical about taking  an injection.  All good so far .. started in early November 2017.  I did use a fantastic foam recommended by my GP while impatiently waiting and suffering to get Stelera. Working from the inside now :))"
