Hi
my mum has the same type of back problem you stated. She was refereed to the ma who requested for the prognosis of her condition , as she's healthy and only gets discomfort from time to time her consultant wrote in the requested medical report that surgery or any treatment wouldn't be necessary (which was main thing ma wanted to know ). We received an email from co today letting us know that her medicals had been cleared.
So basically when it comes round to submitting medicals id suggest that you have ready reports from your consultant outlining that in's and outs of your case specifying if any medical intervention is needed.
good luck
