The most common areas are my lower right
lung, my chest
next to my right
armpit, my upper right
lung, and sometimes the lower left side
of my left lung.
The pain is sometimes not very noticeable but sometimes it is clearly there. It lasts for a few seconds then goes away. Breathing in and out usually does not affect the pain, or when it occurs. I have had fears about my lungs before because of my smoking history, and I've gotten myself checked out at the doctor.
