Surgery doesn't usually resolve all related factor for TOS pain & symptoms.

Myofascial pain, trigger points, other c spine issues, or spinal misalignment's, poor posture that contributes to a circle of pain.

If you can seek out a highly skilled and knowledgeable PT, or chiro, or body worker in your area, I think you will be better off with someone nearby.
The chiro I went to used a variety of modalities & manual therapies as well as adjustments to help me.
The other clients I talked to while in the waiting area all said they felt he had special skills.

It takes a lot of time to repair/resolve the damages from TOS , and a quicky round of treatment isn't going to last. IMO.
