Is This Gyno or In My Head?

Alright I could be totally freaking out for no reason but I know this stuff is no joke. My nipple has been popping out more than usually and has some hang to it instead of being tight to chest. Right side doesn’t have this issue but also right side is a little stronger. I’ve felt around and it seems like no disc I feel something but could be the nipple if it runs deep. Also it has been hard like all the time.
Please don’t judge just looking to see if I should take action or if I’m freaking over nothing

How about go to the physician rather than asking strangers on a forum? I ask this in a polite way.
