I’m not sure what type of doctor to see: I used to work at an ice cream shop and during my time their I pulled a muscle in my pecs. At the time I self

Medicated on Tylenol for a month and eventually the pain went away, I have full mobility. However every now and then I feel a lot of pressure/tension in my chest area, sometimes I “crack” my chest like people “crack” their back. I worry that it could be from my muscle that I pulled; I don’t recall feeling this way prior to that incident. Which kind of doctor should I see to have it checked out?
