My L5-S1 disc burst on Halloween 2006. I opted out of surgery and to have a cortisone epidural injection instead, and continued down that route for the past few years. When the cortisone would stop working, I'd take painkillers (Ultram... nothing too serious) if I needed them. When it got bad again, another injection. I was planning to have surgery in January, but decided to do PT instead, which seemed to help until I realized I couldn't afford it. I just had another shot, and am about to move to the UK, so I have the same questions/concerns, actually.
When I told him I was moving, my doctor said that the UK is fond of the cortisone injections and shies away from surgery for disc herniation. Whether or not that is true, I have no idea. But it was nice to get a little heads up about what to expect.
I'm most looking forward to having other options now... acupuncture, massage, physical therapy, injections, without paying an arm and a leg for them as I have been doing here.
