I've been having lower back pain for about 3 weeks now. It started from nowhere, I was walking to the bathroom at work and all of a sudden I had these sudden shooting pains in my lower back (like, right down around the tailbone) that radiated through my ass down my thigh. My leg started feeling a little numb/strange by the end of the day. The pain was not constant either, it would come in bouts of 5 or 6 flashes of pain and then get dull. The next day it seemed fine in the morning but was the same (a little milder) by the time I went to bed. During all this I was doing Muay Thai and BJJ, it did not bother me during class. After about a week and a half or so of a dull ache in my lower back I saw the doctor who suggested something was out of wack and pressing on the sciatic nerve. Prescribed me anti inflammatories, stretching, heat/cold, basic physical therapy type stuff. I've been on the anti inflammatory for a week now, twice a day, 500 mg each pill. My back has not really improved. It also has not gotten any worse.
I was worried about scoliosis since in high school I had a 33* curve, which was corrected with bracing down to a 27* curve by the time I sopped growing. Is it possible that it's getting worse? I asked the doctor and he dismissed it as unlikely. It also doesn't seem like a slipped disk (which I hear are incredibly painful and you can't move). I have full range of motion, but a dull ache. It seems to affect me most when sitting for long periods of time or lying down when going to sleep. I plan on calling the doc again on Thursday (when I've finished the meds), but would like any input.
Edit* Forgot to mention I have not been lifting during this time, just the MT/BJJ. The last time I lifted was about a week or so prior to the initial pain.
