Thanks Rayhoop... sounds like our injuries are qute smilar. However my post-op treatment was non-existant 4 years ago (depite having private healthcare!) so i was never told i was supposed to have physio, or any follow up pain management treatment such as injections etc. Before my surgery i was told it would cure my problem and i'd be back playing football in 3 months, but a year later and i was still in agony so i had another scan and was told that the injury wasnt getting any worse, but didnt look much better - so the surgery was a failure really. My next course of treatment would therefore have to be a titanium disc replacement, both the doctor and I were reluctant to do this as i was only 24 so it hasnt progressed.... but im sure this will be on the cards in the future.
In terms of exercise, im extremely limited in what i can do... i cant do any running or impact exercises - with cycling seemingly the only thing i can do without injuring myself further... but it just takes so long to do that i dont bother half the time. I've got no patience to do pilates/yoga... i know its no excuse but i cant put my mind to non-competitive exercise
So onto the zed... everyone that's mentioned about the zed being very comfortable... you're right. Thinking about it i do find it very comfortable and never get any pains while driving (Nurburgring and back in 36hrs was easy!)... so maybe it is simply the entering and exiting of the car thats causing me problems. I'll make a degtermined effort from now on to do this sensibly to see if it improves things.
Thanks everyone.
