I want to treat my turtle neck.

Maybe because I've been using my phone for too long, my turtle neck has gotten worse recently. ㅠㅠ

Even when I consciously look at the showcase, I try to straighten it out. However, this effort alone doesn't come easily.

My shoulder hurts so much right now. I don't know how to treat it.

I heard around that I should receive manual therapy. Will I get better if I undergo manual therapy?
