Shoulder stiffness

My shoulders are as stiff as a rock, and I always feel a dull ache and fatigue in my neck and shoulders.

It looks like there are a hundred bears sitting on my shoulder haha

I remember the words of the Chinese person who used to give massages there in the past, saying that the stones felt like rocks and telling me to come oftenㅋㅋ

I think it's because poor posture from using the phone and computer has become a habit.

I'm wondering if acupuncture would be effective when experiencing severe shoulder stiffness.

It may not be a fundamental solution, but will acupuncture make me feel a bit better?
