Hi guys! 

Bit of background. When I was a child I had cancer, recovered well and have been relatively healthy since thank god. 

But anyway, a couple of years ago I started having trouble with my back. I can only describe it as a constant ache all the time combined with like a sharp stabbing pain that comes completely out the blue. It quite literally stops me from being able to walk properly, takes me ages to get up, it's just a massive pain in my backside. I've been given repeated painkillers for it, Codeine, Tramadol etc but it does nothing. Anyway my doctor finally refereed me for an MRI scan to try and get to the bottom of it. That was 5 weeks ago and I still haven't had the appointment through yet, what is the average wait time and is it worth phoning the doc to check on it? 

Thank you all
