Where to begin? I have been troubled with lower back pain since at least 2008. It is a deep ache in the lower back, sometimes radiating to the hips and outer legs just below the knee. Other times, it is a tingling and numbness in the left foot. Lately, any sort of physical activity (even sitting or standing too long) seems to trigger an episode which lasts for days. Recent therapy for early osteoarthritis in my knee aggravated the back, and so I stopped. Neither 600 mg. Ibuprofen (3-4x day) nor applying a heating pad provide relief. It feels better lying down. Short walks and a series of visits to the chiropractor seem to help. Early on, my PCP sent me for a lumbar spine x-ray. The results were degenerative arthritis in the L1/L5 vertebrae. A few years later, the PCP made a diagnosis of sciatica between L1 and S5. He then sent me for an MRI. After recent review of my records, the PCP determined facet arthropathy at L5/S1. He mentioned mild lumbar levoscoliosis and possibly S1 or S2 radiculopathy. Given my history, the PCP is now talking surgery. This scares me. Should I see a neurologist and have nerve conduction studies? Has anyone had a similar experience? Glad to have found this website, and thanks for listening!
