Gynecomastia Growth?

[Bcup breasts]

I am relatively new to posting much here. I am wondering about what feelings in the breast do you have when you are growing? I have gradually grown since I developed breasts about 4 to 5 years ago, and never really felt anything. But within the last week or so, I have this feeling in my breasts, that I can only describe as a "full" feeling, especially going towards the underarm. Has anyone had this type of feeling with growth?

the typical sensation some describe as being "cool" and unsettling. 

I describe it as "Microscopic Poprocks" going off in the breasts. 

I also have a feeling of discomfort that includes a "pushing sensation" and as you describe a "full" feeling.
