I have osteoarthritis in my spine, along with spinal stenosis as diagnosed before my first and only Reclast infusion last April. Since the infusion, I have had severe pain in my lumbar spine and sometimes hips, along with sciatica. The newest MRI of lumbar region showed a lot of worsening in lumbar area. I think Reclast has a lot to do with this and I just hope it will modify over time, I mean the pain. The stenosis is forever.
