what you're describing is quite common, especially in students or professionals who spend long hours sitting in poor posture.
This sounds like postural cervical strain or early cervical spondylosis due to:
-Prolonged sitting with head forward (textbook/laptop position)
-Poor back and neck support
-Possibly weak neck and shoulder muscles
Next Steps
