My neck, spine, and ribcage seem to be the last areas to start loosening up. The Chinese vacuum cups are working really well on these areas. They help to pull the muscles away from the ribcage. They work really well on the neck as well.

I think the reason lying on foam rollers never worked well for me, is, they just put too much pressure on everything and caused flare-ups. These cups pull on small areas of muscle and fascia so they gradually loosen things up. I use them daily and keep rotating the areas I put them on. It's kind of like connect the dots.
