I've been using these Chinese vacuum cups directly on the thoracic outlet area. The sides of my neck, and the upper chest and clavicle area. It's pretty intense. I can't say I enjoy it that much but it needs to be done. I've heard cupping called, "Myofascial decompression" so we'll see how much it helps.

So far, it hasn't made my symptoms any worse, and my movement is improving, so I think I'm on the right track. These areas get really purple after, so that tells me it's pulling a lot of stagnant blood out of there. I've had surgery on one side, so there's a lot of scar tissue there as well. It seems to be softening up some from using these cups.
