I have low vitiman B levels, low vitamin D levels, had an idiopathic pulmonary embolism(blood clot), low iron; thus i am loosing iron and I am a 46 yr old male so they are looking for a GI bleed, and sometimes i have energy and sometimes not. I just would like to find a cure or understand what I have. Any suggestions where I should go? I feel like I am just a lab experiment at times and would like to understand what is really going on. Any help is greatly appreciated.
