Re: Dull pain when breathing
You should freak out since you are a smoker -- you do know better, and you can make a conscious decision to quit. My mom died of lung cancer and she definitely suffered. No easy way to put it....and I won't sugar coat what you already know what CAN be an eventual outcome in your future, not at this time.
Go to the doctor, get an x-ray and put it to rest. It could be many things from TB to bronchitis to anxiety to heart disease to indigestion to muscle strain to partially collapsed lung (continual pain, tho).
GO!! No one can diagnose you on these boards, sorry.
Let us know the outcome.
It's all a matter of perspective!
