Welcome
So sorry you didn't have a good result. That's not a good thing to be stuck with. It sounds pretty bad at your stage right now. I pray you find something to give you relief. Probably not a lot right now but don't give up.
It may not happen overnight. Unfortunately you may be in for a long recovery. Nerves take a long time to heal. TOS is a challenge for patients and health care providers. Be careful who you let work on you. Ask if they're experienced with TOS patients.
Don't know how long it's been since you had your surgery.
I guess pain relief is most important for you right now. I never really got comfortable in that department.
Sleep is also important, if you can get some of that.
Nutrition is also important, and water consumption.
Medications may be most helpful right now. You have to do what you have to do. Be cautious though. I never found a comfortable regimen. It was just 24/7 suffering.

No fun
I didn't have surgery for bilateral TOS. I just know it's a life-altering change. A continuous work in progess.
Don't push yourself too much right now.
