Having a bad back sucks. Hopefully they can figure it out and get you fixed up.
I had Sciatica so bad that I couldn't stand more than a minute or two. I was told it could be fixed with physical therapy and exercise so I tried that but it was just a waste of time. Finally my doctor referred me to a neurologist who gave me the option of surgery. I had a Microdiscectomy about 10 years ago and it was the best decision I ever made. It's a laser surgery and I didn't even spend the night at a hospital. I was out of work for about 2 weeks but I work an office job so it could be longer if you do something more physical. Hopefully something like this can fix you up because it's not nearly as bad as what people think when they hear "back surgery".
