Hiya Jackie and Gav,
I have a long standing intermittent problem with itchy skin. It's most evident on the crown of my scalp, shins, mid to lower back and occasionally arms. It started prior to my PCa diagnosis when I was under investigation for another health issue and feeling quite low. I convinced myself that it was a symptom of the cancer, and asked one of the consultants I saw if this could be reason but he said he'd never come across it before. I now feel that it flares up when I'm under pressure or anxious. Infact, I'm itching as I'm typing this post ! (I've got appointment on Tuesday with oncologist as it appears I now need RT) I'm not saying that this is the case with your Gav who is obviously suffering if he has been prescribed diazepam, but if it's helpful in any way to yourselves or others then I'm happy. I really hope the situation improves for you both soon. All best wishes.
