So been dealing with bad back pain and spasms for the past 6-7 months. Decided to go see a Therapists once the crunches, stretching and deep tissue massage did nothing.

Seems my arch on serve and too much knee bend (some local coach observed) has been causing the excessive twisting in my back where one of my vertebrae is touching a nerve causing the discomfort.
Its to the point where after an hour, I can barely walk and have to crawl out of my car after I am done.
So lots of physio and core strengthening. I figured my core was ok as I play goalie in ice hockey 2 time a week and play tennis quite a bit in the summer.
I will put a vid of my serve for you guys to view soon.
Thanks
It wasn't until your post yesterday that I realized you had not had an MRI yet.
So the diagnosis of spinal stenosis is still in doubt.
It sounds like you are are on the right track with your specialist visit.
Hopefully the problem will turn out to be a "non-specific" back pain issue, that will respond to physical therapy and exercising (and even most cases of spinal stenosis do as well ).
"In 95% of the cases of low back pain no specific physical abnormalities are found by additional diagnostic investigations that may explain the low back pain; this is why it is called “non-specific”. This includes muscle strains and back sprains. Specific low back pain is low back pain caused by structural abnormalities such as a herniated disc, a fracture, [spinal stenosis] or a tumour." -

Clicking on the URL above leads you to the ITF tennis site on low back pain. It sounds like you may already be in physical therapy, but reading the page may give you some more ideas in your rehab, and strategy for your subsequent return to tennis.
Right now it is getting way ahead of things, but after seeing your tennis serve videos it seems like you overall have good technique. But you have a powerful frame - you will never look like Murray. But is there a chance of losing a few pounds to take some strain off your back?
Also, with your powerful frame and hard serving, I think you really would benefit from really strengthening your back muscles - ONLY IF AND WHEN YOU GET MEDICAL APPROVAL.
That is beyond the physical therapy that will get you back to doing activities of daily living, and even in good enough shape to start hitting, you likely will need REALLY strong back muscles to prevent you from having a recurrence once you start serving.
That means doing squats and deadlifts. No, it does not mean you have to be lifting twice your body weight or more - but a long, slow program to even get you up to lifting "just" your body weight may give you the back muscle strength you will need to continue bashing serves.
And after a period of strengthening, a power program of throwing a medicine ball may be a better preparation for the rotational forces involved in serving, rather than relying on just serving alone as your plyometric exercise:

Best wishes that all goes well!
