For the last few months I've been suffering from sciatica on and off, but these days it is getting worse and worse. My disc problems are in my thoracic spine. I had a two-level thoracic discectomy in July. Prior to my surgery, they did a lumbar MRI, which came back perfectly normal...no herniations or stenosis. When I mentioned the sciatica to the surgeon, he said it's not caused by the thoracic spine and that was the end of that.
As I said before, it's getting worse and worse. I'm in the process of being diagnosed with ankylosing spondylitis, and I know SI joint dysfunction is a common finding with this disease. That being said, can problems with the SI joint cause sciatica? It's the only thing I can think of, being that my lumbar spine looked fine. I am meeting with my PM doc today and a rheumatologist in two weeks.
