Funny, well not funny, but I had a situation were I couldn't walk or even stand for any length of time without extreme pain. I went to a slew of medical doctors, everyone from PT, to Spinal surgeons, to pain injection therapy with absolutely no results at all. I finally talked the VA into scheduling me with a chiropractor and within three weeks the change was unbelievable. After all that time I am just about back to normal, I had disc movement (4&5) that was pinching nerves leading to my legs.
Just a bit of something that I learned. I also thought that all Chiropractic treatments were the crash and burn type. Violently attempting to reposition the spine. I got very lucky because I had no specific Chiropractor in mind so I choose one that was closest to my home. She didn't do the sudden movement system she used what I can only describe as a tiny jackhammer. She used it to gently realigned my spine with a little vibratory hammer. It took a few visits to get thing working well again, but she did it with absolutely no pain during the session. Ask around and see if you can find a Chiropractor that uses that method. It doesn't have to slam things around to work. So now one year later I can walk for whatever amount of time I want and stand in lines with only the slightest ache in my lower back. Not even enough to talk about
