I'm doing some vacuum cupping tonight on my neck and shoulders. This, along with joint mobility exercises and self-myofascial release are the 3 things that help me the most. After 34 years of this, improvements come very slowly, but they are possible. I've done a lot of videos about this stuff. If you're interested here's the link.
