I just read your New Member Introductions. It is rare that those who follow the PCS forum read New member Introductions.
You complain about head forward problems. This is not uncommon. If your PT has not been able to help with this, you need to find a different therapist. Upper cervical chiropractic may help.

Be careful if you try a generic chiro. The twist the head and pop the neck is too aggressive for the subtle upper neck injuries many have.
You also need to be very disciplined with your head and neck posture during rest and sleep. You can undo any improvements by bad posture during sleep.
