Hey guys,
i am 18 years old and i have quit smoking for 2 months now. I used to smoke marijuana everyday and about a pack of cigarette every two days. Thankfully, i was able to quit all that stupid stuff for the sake of my health. I would get really badly congested (blood in mucus), shortness of breath and (rarely) a pinching sensation in my chest. I have neither had any shortness of breath nor any pinching sensations since i quit. But every once in a while when i blow my nose there is blood. It never drips just stays in the back of my nose. It's frustrating because i have made a great deal of sacrifices to quit and still one of the symptoms hasn't completely gone away and i sometimes get really stressed out about it. I saw a sinus specialist and he didn't seem to see anything wrong.

I really badly seek advice,
thanks in advance,
Andrew
