lisa....I have degenerative disc disease but am much older than you. I have tried everything and nothing really works 100%. I had to go on full-time disability from work two years ago because of the pain and spasms.
I do believe it's unusual for someone your age to get ddd unless you have had a severe injury of some type. Maybe the trauma of the tailbone break is just now showing up because you are aging and your discs are beginning to compact with a lot of sitting and also gravity.
The discs dry out as we age (that's my problem) and the discs compact pinching the many nerves that surround the spinal column. It's not a pleasant thing to contemplate for the future. I also have numbness down my left side like you.
No one who doesn't have ddd can even imagine the pain....Not even your husband, parents, bf or even your doctor. I have tried almost everything in the past 7 years (injections, nerve blocks, heavy pain meds, etc.) with little success.
Just because some of those options did not work very well for me does not mean they wouldn't work for you. I have been to three different pain management doctors and each recommended different approaches. I will warn you that none of the procedures are very much fun to go through.
Now I am trying massage and acupuncture but have not had enough treatments to get relief yet. I have heard that spinal stretching might help ease the pressure on the discs but I have not tried it yet. Surgery was not indicated for me (specifically, disc fusion was not practical). I can explain in detail any of the procedures, even surgery, because I have been throughly briefed on them or have gone through them.
I am truly sorry that you do not have insurance because that means you could be facing scary expenses. My wife and I estimated that the surgery alone for the fusion would have cost us $5000 out of pocket with insurance.
Good luck, I hope you find something that works for you. The suggestion by sillyakchick makes a lot of sense and could solve your short-term pain. Percocet is the minor leagues of pain meds for back problems. Just wait until you get bumped up to oxycontin and morphine. They help with the pain but could end up screwing up your life.
