my question is, obv do i have a serious health condition like emphysema?

[XpGreaterthanVista]

I began smoking marijuana heavily (every day 2-3 times) from 2002-2003, and on and off until recently. i also smoke cigarrettes heavily for last 5 years (1/2 - 1 pack a day)

about 4 years ago, I wake up one morning with a sharp chest pain that would intensify in different positions.  for example, if i tried doing a sit up, it would hurt more.  the reason i didnt get it check out was because it went away, and i was very busy with college and my job as a poker player (quite stressful job).

For the last 4 years, this pain came and went at times, and for the last 3 years it persisted a lot more, and one day after twisting my body and chest, i heard a clicking sound and feeling in my chest (similar to the cracking of a knuckle) and the pain/discomfort would be eliminated temporarily.

somethings to note-
-23 years old, turning 24 in august
-recently quit smoking marijuana and cigarettes for about a month (cold turkey)!
-been coughing up mucus particularly during/after excercise.  but when i experience the discomfort in my chest area, usually i can stretch my chest and hear that clicking sound/feeling and the chest discomfort/pain goes away temporarily
-i have had bronchitis 2-3 times in the past.
-i have gotten quite overweight (5'9, 185lbs) in last 4 years from bad lifestyle, obviously now i just started to change lifestyle, and i feel much better then before.

my question is, do i have a serious health condition like emphysema?  and what is that clicking sound in my chest that takes away the discomfort in my chest (been happening on and off for last 2-3 years).

i will see a doctor soon but can't for the next several weeks because i will not have health insurance until than.

Please advise for now

You have made some positive decisions and changes in your life.  The next one will be to see a physician.  It is difficult to explain what you are describing without a good physical examination and possibly a chest x-ray.  Emphysema is possible, but highly unlikely.

I was just diagnosed with bronchitis. I wanted to know if it is contagious as I live with my fiance and am concerned about him getting it. we have not gotten close or kissed since this has started, but we are still concerned.
