Do not try to understand the report on your own. It sounds like you have sustained some trauma to your spine in the past. I have to assume you are athletic and perhaps had some sport injuries. Or you are a tanker or helicopter crew member who has seen a few hard vertical seat smashers.
Depending on where you are stationed, you are likely going to get to see a Dr on post again sometime in January. Unless you already have a chiropractor referral. If you do, calm and see if they can get you in today or tomorrow.
Stenosis is a narrowing of the spinal column. It is caused by those shifted discs. That narrowing can cause pain. "Neural foramina are widely patent" means all is well. "Levocurvature of the thoracic spine" means you have a slight leftward curvature of the thoracic spine. The thoracic spine starts at the bump on your neck and goes down to where your lumbar curves in towards your belly. The surgical note means that should you begin to exhibit constant pain, surgical intervention may be necessary. Mack, I hate to tell you this, but you're not straight. Well, at least your back isn't. :D
You are about to get out of PT for a while. I just hope you are not in flight school. You may have to sit out a rotation if you are currentry hurting. Or perhaps a good chiropractor and some physical therapy can get you through to the end. Then you can consider the therapy.
Good luck and thanks for helping take care of our country.
