Absolutely. Nobody knows your lifestyle, eating habits, activities of daily living, and your body better than you. If we feel like our doctor doesn't know enough information about us to determine what is wrong with us it is up to us as patients to inform them as much as we can. I am what you'd call a babbling patient. I will repeat things as many times as necessary and sometimes even give too much information. Even with that I still think they sometimes miss things but I've done my best and after that I go with my gut instinct.
Physicians are not gods, they can't save everyone, nor will they be right with 100% of their patients. But to those Physicians out there who truly listen and try to find a cure-- I give much respect to.
