Ok, perhaps not Itchycoo Park but definately itchy me!

For the last 6 weeks or so I have been itching and itching and itching. The top of my feet and my lower legs and the palms of my hands. No I've not changed washing powder, softner, soap...not changed anything actually but still I itch and I itch so much that I draw blood. Now this is driving me nuts...I smother myself in cream, oils and other assorted things all good for itchy skin or so they say. Do they work? NOOOOOOOOOOOOOOO!

Anyone got any suggestions for me please???
