Is it a bone problem? You need to remember whether there is such a difference before you exercise. Touch it again to see if it's muscle or bone.

If uneven muscle development is caused by uneven exertion, then dumbbell one-arm exercises are needed.

Practice single-arm lifting, or double-arm lifting with different weights on both sides, shoulder birds with different weights, etc. In short, you should strengthen your shoulder imbalance practice.

As far as the current situation is concerned, it is not recommended that you push your chest again, because pushing your chest will also exercise your shoulders. You can push your chest with a barbell. The stress on both sides is balanced, and you can't highlight one side of the practice.

Correcting needs a process, at least about 3 months. Don't worry.

After correction, we should pay attention to the balanced exertion during exercise, and we can also use combined instruments or barbells. When you have bad control, you'd better not use dumbbells, because dumbbells can easily cause uneven force.

Good luck.
