Get the doc to write you a script (or order) for physical therapy. Work with a PT on your exercises. That way, when things start spasming after a few minutes, you'll have someone to corroborate what happened to you. Sometimes, doctors hate to admit they might be wrong.

As for the spasms, you might ask to be prescribed Flexeril or some other med to help with the spasms. After my surgeries, I was helped with therapeutic massage.
