I've been using these Chinese vacuum cups for a little more than three months now and they work really well on scars, and scar tissue. Even though my TOS surgery was 22 years ago, using the cups directly on my neck scar has really loosened things up. It feels the best it's ever felt. It still needs work but I'm getting looser all the time. I think on the neck, cupping works better than massage.

I also have a scar from having open heart surgery last year and I've been using the cups on that. It was very painful at first but it's getting better all the time. The scar has faded and loosened up a lot.

When I first started using these cups, I was afraid it might cause a TOS flare but so far it hasn't. In fact, I haven't had TOS flare since I've been using these. Hopefully I didn't jinx myself by saying that.

Joint mobility is good stuff and it works even better when you put some of these cups on and do it.
