"Skin rash"

I have been suffering with a skin rash for the last 15 months and rather than improving after being seen by a consultant it is getting far worse. It only affects my face ( it did affect my hands badly but they have now claered up ) but at times my face is so painful like a burn I find it difficult to speak, eat etc. I work so it makes it really embarassing to be seen it is distressing and extremely embarrasing. I have never suffered with any skin condition and neither have any of my family. It takes a matter of a day or two to flare up and weeks to try and settle it back down each time takes longer. Firstly I was told it was psorasis now apparently its dermatitis. I have had blood tests, patch testing which was a joke. . Rather than trying to find out the cause of the problem I have been fobbed off with prescriptions to mask it - sometimes 4 items on a prescription at one time so pretty costly. Any petrochemicals creams make it worse. I feel my consultant hasnt got a clue and rather than ask for a further opinion - I did pay to see an immunologist in September who advised a course of action that has hasnt happened yet ) we just keep going round in circles but meanwhile I am getting worse and worse rather than better. I have now had to almost beg my GP to refer me preferably to Nottingham QMC ....
