About a year and a half ago, I felt an unusual growth. I felt hard tissue under the areola and occasionally my chest used to hurt a little. As I went through a similar situation in puberty, I assumed it was about growing breast. By the way, at puberty my breasts were quite swollen and there was quite a big bulge under my shirt. Especially since I was pretty skinny. I was not allowed to touch them, because I would see the stars in pain. This lasted for about a year, only to gradually recede and the chest then became almost flat. I didn't pay any attention to it, except that I liked it and I showed solidarity with the girls, because that experience showed me how they feel. In elementary school, in biology class, the teacher had a lecture on sexuality and puberty. And she mentioned that boys can also temporarily grow breast, ie swell their breasts. And I wasn’t the only one in the class with that problem. My cousins went through the same thing as me. That's why it didn't bother me.
By the way, now in recent times when my growth has started, I had a premonition that it would continue. And I began to document myself and chronologically follow any changes. So don’t mind if I put my picture here every now and then. It might help someone with a similar situation if they come across this forum and start looking for answers or support.
Here is one chronological picture of the change of my breasts back a year.
