question: Age 37, 5 feet tall, 160 pounds and extremely active. I started having low back pain (no injury) in December so I went to the chiropractor for adjustments and the dr for some pain releif. I took the medication (muscle relaxer and anitinflamation) for about 2 weeks and continued witht he chiropractive until about March. The pain went away until about 2 weeks ago. It's again very painful, but I also noticed that I have been having brown spotting for the last few months also, so I though maybe that might be the cause of the low back pain.
