Can pushing on nipples/pecs trigger gyne?

[paranoid]

Since I found this website, I read some of the symptoms of gyne.  So of course I pressed down on my nipples (went straight down--nothing hard underneath) and pushed on my pecs to see if I have it.  I need to lose some weight, and it appears that it is just fat--when I lean over or lie on my side and feel, everything moves easily.

But because I did this so much at first, I thought that I felt a little sore, although I have started working out again so maybe it was because of that.  I was testing throughout the day.  I guess my question is this:  can pushing on your nipples and pressing/poking your pecs "trigger" gyne?  Sorry if this sounds too paranoid or stupid, but that's me.
