Oh MPB I'm so sorry you're in so much pain. It's the most hideous thing to have wrong with you. Anything else you could at least get some sympathy for but it's not even easy to talk about it with close friends I find. And because you are not actually in danger of dying from the damn thing, the NHS seems to put you on the time wasters list. Totally unfair.
But hang on in there buddy and you will get back to normal life some day. When you have the strength, make a pest of yourself and get in to see that surgeon as soon as you can. Wishing you strength and relief soon. x
