The Reality
'Tech Neck' and 'Bad Posture' are reductionist labels that aren't supported by evidence. Your neck is designed to move and look down. Pain here is usually a mismatch between Load (stress/position/duration) and Capacity (strength/tolerance).
The Structural Root
We use Manual Therapy not to 'fix' alignment, but to desensitise the area and open a window of opportunity for you to move freely again.
The Nervous System Root
The Upper Trapezius muscles are highly reactive to emotional load. We use Indian Head Massage to down-regulate a 'High Alert' nervous system, treating the stress driver rather than just rubbing the sore spot
