I am a long term sufferer of DDD but recently I have had the worst flare up which has lasted 3 and a half months.
I'm not sure what's up with my back now, but I was in a collision with at Deer which came through my windscreen about 10 days before it kicked off. Now when I do a certain exercise which I was taugh previously by a physio ( you lie on your back, knee bent and almost do a cycling motion)' each time I do this I have a horrible click in my back, it's every time I move my left leg, it sound like bone on bone, it certainly very different to the normal pops you get when moving. I'm not sure if the accident may have caused something to pop out of alignment and that when I thought about a chiropractor, but I'm just guessing at what might be wrong. My doctor has assured me that I will get back to a baseline pain but as time goes on I struggle to see how it can now change.
