Odd back pain with unrelated paresthesias /numbness? Could it be injury?

Wow! You have been through the wringer. That's a lot of tests to have done and pay for. LOL! There is a phenomenon that happens to a lot of people who have pain. You can have a problem that causes you to have pain, the problem that is causing your pain heals but your brain has been reprogrammed to believe that you are still in pain. It's a sucky thing and I don't know if there's any real true treatment for it. You will find tons of books about it and how their particular system works. It may be time for you to see a pain management specialist. The tingling and even the leg numbness sounds like it's all due to a pinched nerve or nerves. A lot of people have a pinched sciatic nerve but there are other nerves as well that can be pinched that will cause pain going down your leg or like in your case, numbness and tingling or even burning. You may get good results from an epidural injection in your lower back. I think the doctor will want to do an injection of steroids into those each bulging discs in your lower back and your neck. There are also two drugs on the market that can help with nerve issue. One is called Gabapentin AKA Neurontin. The other one is called pregabalin AKA Lyrica. Your pain management specialist will probably want to put you on one of these two to help with your conditions. Neuropathy can also happen when someone has diabetes and you did not mention if anyone tested your blood sugar. You should probably have that done just to rule that out, and it's a simple blood test. I have one question about your physical therapy. You said that when you go and only lasts about 24 hours. But you're supposed to be doing these exercises at home as well so are you doing them at home and if so are they not causing you relief in the same way they do when you go to the physical therapist? You could also purchase a TENS unit which works well for chronic pain. It's little patches that you put in the area of pain and it's plugged into a box and it sends stimulating electrical zaps. I get a great deal of pain relief from my TENS unit. Unfortunately the minute it stops my pain returns. I really hope you find some relief. I've had chronic lower back pain for 11 years and in the last couple of years I have had a couple of other diagnoses that also cause pain. So I live with a lot of pain and I'll tell you, I know pain! Hehehe

I am informed the numbness down the front and side of my thigh (about the size and shape of a rugby ball) is quite common where a nerve is trapped in the lower vertebrae and for a few years now this has been present for me and another numb spot has also presented last year (about tennis ball size ) on the other outer thigh.  The back pain is ever present and is worse sometimes than others and has restricted my mobility, especially walking for any distance.  I am loath to go for any surgical option as the outcome is unpredictable.  However, the condition is not one which is life threatening, just a burden and the numbness presents no problems.  However, I have been asked to report in if the numb areas in my legs increase as obviously the organs in between must remain free from this and that would be more serious and perhaps my options then would be surgical - however, so far, so good.  Incidentally I had a lot of AFib and now have a pacemaker with no further heart related problems for a few years now - it all came at once from previous excellent health.
