Hi Rachael,
Your post is heartbreaking. You are so young to have gone through that. I was 46 before the nightmare started and had raised my family. I had fusion surgery and I can tell you that I had leg pain for quite awhile after the surgery. The dr. told me that so much is disturbed with that type of surgery, it is to be expected. He told me it would get better and it did. So, give it time.
I never took the strong drugs you took but can only imagine how it must be to get off of them. I have had drs. suggest stronger drugs but I fight it all the time. I had almost 2 years of no pain and it was great but the unfortunate thing, I have pain again, at another spot I suppose. I'm waiting to find out test results from a myelogram this week.
From what I have read, surgery to fix an injury has a better outcome than my situation, DDD (degenerative disc disease). So, I don't know the answer to your question, whether you will get better but I'm thinking you will!!!!!! and, hoping I will.
You will have better days, I know you will........
