For the last 3 weeks or so, every once in a while, I have been having horrible back pain when I wake up. It doesnt happen every morning, but about every 2-3 days. The pain doesnt wake me up, but when I wake up, it feels like all the muscles in my back are tightened. The pain forces me to get out of bed and stand up for about 10 minutes. Sometimes its in my upper back, sometimes its in my middle back. Also, recently I have had some ever so slight tingling in the front and left side of my lower left leg , and in my left foot when I sit down. I dont keep a wallet in my pocket, so I know that isnt causing any problems. Any one have any suggestions as to what my be causing this? I dont know if I should just go see my general practitioner, or go to a chiropractor. I had someone crack my back about two weeks ago, and I felt so much relief, I cant explain it. Any recommendations?
