Home care methods to reduce trapezius muscles

I tend to have persistent pain in my shoulders and back.

Maybe that's why my trapezius muscles are really raised.

I've seen a lot of posture correction and home workout methods on social media.

I didn't see much effect.

Are there any home care products that can relax the shoulders?

Things like massagers... or products that relax muscles.

I have a headache, probably because my trapezius muscles are stiff.

I really hope there is a good way.
