David S. Campion, M.D. I practice in an unusual branch of medicine called electro diagnostic medicine usually shortened to EDX. I love this specialty because it combines two parts of medicine that I have always wanted to practice: I get to chat with my patients, and at the same time use my wide experience of medical science to help them get information about their problems that will help them and their doctors make good decisions. www.drcampion.com Please visit my website[ http://www.drcampion.com ] for more details on Electro Diagnostic Medicine.
