I love how clearly you laid out your history

So are you having any kind of good PT now??

My thinking is - you didn't have these symptoms before - so you should be able to turn it around {with an excellent care team} without surgery.

How is your overall posture? upper body posture?
Bad Habits & such- holding a phone with shoulder to ear, desk not ergonomically set up, sitting crooked or tilted often

That is one main thing to address, if the head or upper body is rolling forward or hunching and causing some of the trouble. This happens over time and takes a long time focus to turn it back around.

No Drs mentioned clots or anything??
