With the exception of a minor smoking
habit I'm working to abandon (4-6 cigarettes/day), I consider myself healthy. About 10 months ago I noticed a slightly nagging achiness throughout my chest
. It's largely limited to the upper left side, but occasionally is
felt on the right side. I responded by increasing my activity and began quitting smoking. However, I still notice this
pain, which is
dull and in no way prohibitive, but noted. Oddly enough, I don't think it follows any necessary pattern.
