Well, I'm back from seeing the consultant, the plaster cast is now off, and I've been given the all-clear to go back to work.
It'll take up to 2 months to heal though, so he said I should use one crutch to walk with (both if I feel the need), wear sports socks, and keep my walking around to a minimum. I'm also banned from cycling for a month, and hiking and running for two months.
The weird thing was, he asked whether I had a 'normal' diet and I must have pulled a face cos he then asked whether I was 'one of those extreme vegetarians'!
So I said I ate a balanced vegan diet and then got a bit of a grilling about vitamins and calcium! I bet pasty-faced overweight burger-addicts don't have to have conversations like that in hospital
