That is so great that it works for you..
Did you ever see this video where the lady slides the cups w/lube on skin for a massage action also?

She explains how it works to move & flush out the stagnate toxins and brings fresh blood & fluids into the areas.
For those with chronic & esp long trem tightness and spams something like this is what is needed to help clear out junk.
I really think this is something that many with TOS/myofascial symptoms/pain should try, might save on so many PT sessions and not that costly to buy a set of cups.
