I have had lower back pain that also includes pelvic pain. Also my hips burn when I walk. This has been going on for 6 months. Xray showed nothing, MRI said possible infection in L5-S1. The pain is bad enough to cause an upset stomach. Sometimes I can't get up off the couch or bed. No injury to back it just happened in Dec when I picked my granddaughter off the floor.pain does not include legs or arms. I am scheduled to see a neurosurgeon on June 25th. Pain is worse at night. Neurontin doesn't help, neithet does Ultram.
