I have a pretty sharp pains in my lower back while I sit on the floor, or just laying down. Almost makes me sick to my stomach, but I am able to tolerate it ( haven t done anything about it yet). Could you explain to me what this is, and what I should do? Should I see a chiropractore? I m 19 years old, and 120 pounds so excess weight is definitely not the issue. Get back to me as soon as you can, please & thank you!! Alli
