"The premise of EFT" is that ALL negative emotions are created by a blockage in the energy systems of the body. I really need to refer you to their website www.emofree.com as i don't have a lot of time to commit to forum minding. There is more info on that website than anyone could possibly absorb as the founder and other practitioners regularly post anecdotal testimonials (including several on knee injuries) through the search function. My goal was to offer a possibility of help to Garjang.
Practising EFT is simple in it's initial understanding and learning the basic steps. Dealing with people's emotions, feelings and illnesses, as you know requires creativity, compassion, study and excellent listening skills. I recommend anyone who considers themselves a healer should learn about this important tool for your tool kit and try it on everything. It doesn't hurt and I know it works.
