I've managed to get the MRI scans working properly and extracted a couple of images to show the damage to my spine. The lower disk of the two that have gone actually has a tear. The physio is going well, though last week I had a bit of a relapse it was no where near as bad as it was when I first did it, though it did nearly have me off work. Thank you so much to those who have either given a little something or shown support, both are very much appreciated.

New rucksack ordered, it's small 14L which is as much as I need for a summer day walks. The important bit is that it has a frame and a well padded waist belt this will lift the weight of my shoulders and put it on my hips, this reduces the risk of compressing my spine during when walking.
