I have had chest pain for 3 days, on my left side that is really just discomfort and worse when I take a deep breath. I have had a cold where I had a fever of 100.2, disorientation, fatigue, stuffy nose, yellow mucus, stiffness and body aches. I m assuming I have the flu, but with the chest pain I wondered if I had an infection. The pain does radiate to other parts of the body, but I also have Sjogrens Syndrome and Fibromyaglia so it s hard to determine what is new and what is part of those issues.
