Thank you all for replying and letting me know your disappointments. Some of them must be hard coming to terms with even after many years. I must say I still don't believe doctors when they tell me that certain treatments will 'alleviate' the itching and rawness. Nothing ever does and, I am only assuming, that as it isn't a life threatening condition, not too much research goes into why some people are affected, some very badly. I'm 80 now and still want to tear off my face, arms, legs, stomach, in fact any part of my body sometimes. The only thing which helps me is a very short, cool, shower. I was given UVB a few years back and it was wonderful. Alas, due to Covid-19 it is not available in my area. Still, life could be a lot worse, I do love my life.
