I went to the doctor before Christmas because I'd realised that my very very sore cracked and scaling elbows were probably psoriasis, I'd also had a red symptomless patch on my leg for about a year, which a previous GP had said was eczema

I was diagnosed as having P and given a steroid cream, this held it in check but it carried on spreading and I now have a patch over almost the whole of my left palm and some on my right palm, my elbows flare up and the soles of my feet get very sore and scale.
I'm wating to be seen at the hospital and am currently using Diprobase and Oilatum and Dovobet (not a lot as I don't like the long term side effects).
I find Vaseline really helps when my skin gets really dry and is shaling off.
In the last couple of weeks I've come up with sore patches on my waist and collar bone that I think may simply be an allergic reaction to something as they are exactly like the reaction I had to the sticky plasters when I had a 48 hour ECG - I'm hoping they aren't psoriasis as well?
It seems as though I have the palmar form?
Is there anything else I can do/use? any advice?
The only family history is my grandfather, though I was unaware of it at the time, my mother said he did have problems.
