Yes, you must consult with doctor. It may be miner problem. I think that you quitting that’s why you suffer from this problem. But don’t worry every thing will be fine. Go and checkout your doctor. Good luck
Yes, definitely see your dr if you haven't by now. I can tell you though, my chest was very tight and bronchitis stuck around for months and months after I quit.
Good luck and congrats on 8days!
Altho quitting smoking does make some people feel worse before they feel better, with your history I would not take any chances and see a doctor asap. Let us know what the doc says?
