question: I am 28/female, I have been experiencing lower back pain for 2 1/2 weeks. And a headache for 3 days. Today, my lower back pain became so bad I cannot get comfortable. The pain has a piercing/burning feeling on the lower right side. It hurts to stand, walk, lay, and sit. My headache is the worst yet, and I am currently running a low grade fever 100.9 No rashes.
