Ive been sick for 5 days now, and for the first time ive been feeling short of breath, no chest pains, so I chalked it up to anxiety, because all i have to do is calm down and not worry so much about whats wrong with me for it to go away, however I cant talk for too long because my voice ends up dissipating from breathlessness or at least i think its that (all i have to do is cough and i can talk again before it reoccurs), I was a smoker from 09-14 until I switched to vaporizers, which I mistakingly used on the first day and second day of being sick (I take vitamin c reguraly and the symptons werent very apparent), it was that second day i started feeling short of breath. My lifestyle is a sedentary one if thats any help. Also when i blow nose theres almost always blood, but theres no blood when i cough up phlegm.
