Last week saw doctor for lower back, left calf pain, got meloxicam and tizandine for muscle sprain. been taking both medicines everyday and stretching twice but pain still exists and feels worse (waking up). go back to doctor or try taking tylenol?

Doctor can recheck: The more common causes of lower back pain include: back muscle strain, back ligament sprain, fractured vertebra (spondylolysis), slipped vertebra (spondylolisthesis), herniated disc, spinal stenosis, spinal arthritis, urine infection, kidney infection or stone; tumor in the spine, kidney, or elsewhere; fibromyalgia, etc... With such a long list of possibilities, the doctor can examine again.
