Is there any exercises to get rid of hump on the back of my neck? I slouch Sometimes my hunch isn't big though

Improve your posture. This is not worrisome is there are no associated symptoms such as pain or weakness. If the contour of your neck lessens with improved posture, it is important to maintain good posture as much as possible by keeping your head above your shoulders. Focusing on strengthening the muscles between your shoulder blades and abdominal muscles and limiting prolonged sitting will helps.
