I\'m no Doctor (But am a certified trainer and EMT) and I can\'t imagine that pulmonary edema being caused by creatine, as pulmonary edema is usually caused by the heart itself not working correctly, not fluid retention by your blood cells....However, have you been taking high doses of creatine and Aspartame? If so, that could have caused it. I\'s been documented that large amounts of these in combination will realese toxic levels of methanol and can cause pulmonary edema. If your doc doesn\'t know about this, alert him. If you want to know more, look up Charles Fleming as he\'s the most documented case.
