<s>[INST]I have been having shortness of breath, nerve pain, chest pain, and fatigue. I took samples of my saliva and found these: https://www.flickr.com/photos/0000@N00/sets/0000/ Can you tell me what these are and if they may be contributing to my symptoms?[/INST]Hi, sorry the link you shared shows "bad link" ad Chat Doctor. Anyway, your complaints are suggestive of some cardio/pulmonary or other general problem, diagnosis of it would need your brief history, because your age, habits, other disease, predispose your health and current symptoms. For now, I would recommend you to contact your primary care physician and get evaluated by basic cardiopulmonary assessment plans. And best wishes</s>
