I have had a sharp, almost stabbing pain in my lower back for the past two weeks. I thought maybe I had pulled a muscle or something, but it has not gone away. It started in my upper back and I really notice it when lifting or standing for periods of time. At time it feels like something is trying to burrow its way out of my Lower back. Not sure if you can tell me what the problem is ? and/or if it can be fixed at a chiropractor or phisio ?
