I am 25, healthy weight, not as active as I should be. About a week or so ago I got a cold, a viral infection, I had a runny nose, flem, cough, it eased up after about 3 or 4 days. I still have the cough though, had a bit of flem over the few days, but now no flem really. Anyway, I have had a terrible horrifying fear of Blood Clots for a long while and I went doctors yesterday about my cough and he gave me antibiotics to take, I only took my first one a couple hours ago. I keep having this fear that the wheeziness is a clot in my lungs and I am going to die without knowing!!! Please help me! Doctor examined my chest and said it was due to the viral infection. I am so scared,, please,, is it a Pulmonary Embolism? I keep thinking it is, that I am going to die???
