Its not really that hard to understand that this works. Even if you take away the effect that the suction directly has on local vascular and lymphatic circulation, you can also think of the suction as a very effective means of stretching the fascia and tight muscles.
But if you do look at it with a bigger and wider lens, cupping pulls blood into an area. Because of over work and or trauma, or just the opposite of not enough activity, the blood supply to effected tissues decreases and the fascia gets knotted and scarred, further limiting movement and can become a vicious cycle. Putting cups over these areas can reverse these effects. The tissues get saturated with fresh blood while the vacuum pulls stagnant blood out of the area. As new blood is forced into the tissues around the cups the body will begin to develop new blood vessels in a process called neovascularization... this is possibly why cupping can have a lasting effect.
As the new vessels form they will have the capability to feed the tissues with nutrients and oxygen which are needed to keep them healthy and supple. Another thing that happens in this process is a controlled inflammation, called sterile inflammation (you can think of it as a "micro trauma" to the body. Of course these days people think that inflammation is bad and something to always avoid, but actually the inflammatory process is the first part of healing. In this situation the body releases white blood cells, fibroblasts and other chemicals that promote healing. This very temporary inflamation is not a bad thing. As I mentioned before, the fascia and muscles and tendons are also being stretched with cupping. In certain cases soft silicone cups can be used in conjunction with movement, or the cups themselves can be moved around an area or along a muscle.
So , cupping is a technique that works on several levels and has proven to be a priceless tool in my own practice. Of course, effectively treating chronic and or acute injuries with something as simple as cupping is NOT as expensive as a course of meds or invasive surgical techniques... so it's not in the vested interest of the people making billions off of these industries to admit that something like this, Gua sha, or Moxibustion works( let alone Acupuncture and Chinese Herbs).
Some say ancient suction therapy soothes muscle pain; research can’t rule out placebo effect
