I’m a huge proponent of cupping but… that was unnecessarily dramatic/redneck sounding and would make people never want to get cupped. It was a good read but, for anyone that was scared or really turned off by reading that.. it’s very legit which is why many athletes use it.
It’s not dramatic at all and acupuncturists do this all the time. It’s safe and awesome, and can sometimes be painful if it’s around your neck and shoulders when you have knots, obviously. But there are many advanced cupping techniques with very small cups by professionals that don’t make people scream or turn purple for months.
