I'm 18. Late August I felt a sudden pain in my lumbar spine lasting no more than 2 seconds. Since then, I've had this intermittent pain that lasts pretty much a second at a time, from 5 to 15 times a day more or less. It seems to be between the first and second lumbar vertebrae, but sometimes it kinda radiates to the proximities. Several times it hurt when I moved a certain way, but I'm never able to reproduce the pain by moving the same way again soon after. The very first time it hurt, I somewhat felt a numbness on the left leg, and a couple of times I felt brief pain on the left buttock bone (or hip). There were times when it seemed to be getting better. It doesn't exactly seem to be getting worse, however. (There were two occasions these last months when it's possible I worsened everything by certain physical exercises, but I'm not sure.)
I have mild scoliosis; almost sure it's not related. Also, a few weeks before I felt the pain I was doing crunches and I think I may have pushed myself too much. It may be related or not. I've never ever had any back pain prior to that first time in August.
I'm going to see a doctor but I don't have a date yet. In the meantime this is very upsetting. 100% of my discomfort regarding this is psychological, since it's not a debilitating or even lasting pain. I'm worried. It's been months, so it's chronic, right? But at the same time, it has a very weird pattern. Reading on back problems doesn't help much, because nothing fits completely. I was wondering if maybe someone has or had something similar or if any of this rings a bell to someone.
