I went to school for Massage Therapy, I have been giving massages since the 1st Jaw's movie came out and I was hiding behind my Dad's back. He said while your back there work on my neck! lol. I've always been a healer using touch, it when I went to college for it I learned many more modalities. The lymphatic drainage help with sinus, diabetes and the swelling around the legs and feet, fibromyalgia patients get great relief in the arms and hands. You use the pressure of a dime, not to crush the tubes that move the lymph. You can Google it, the only thing is you HAVE to ask the client is they have blood clots or hear conditions. If they do, they need a doctor's note stating they can get treatment. It can kill someone if you don't know their medical history!
