Blotchy

Can't remember last time I got blotchy, Paul insists he's never seen it so it can't be for a few years.  As per usuual , I;ve not idea what caused it, only that whilst sat in the cinema last night (Slumdog Millionaire - great film) I started to feel a little itchy and had that doomed feeling.  sure enough, on greater inspection at home the blotches had started and by this morning I was well and truly covered in red wheals all over.  I'm doped up on anti-histamene and feeling sorry for myself.  Still it usually only lasts a couple of days....
