I'm 25 years old, and I have had gynecomastia (I'm not sure if it has come and gone or I just go a long time forgetting about it) since I was a teenager. I remember my pediatrician dismissing it when I was in school.
I also remember getting it looked at again, either it left and came back, or I just forgot about it until my anxiety problems started, when I was 19 or 20. At that point my doctor even performed a mammogram to be sure it wasnt anything serious and that came back with no results, so I ignored it for a while longer.
The last month or so I've noticed it again (or it came back, again I'm not sure), after a couple years of homelessness, and not exactly living as well as I could. I didnt eat well due to homelessness, the food I did get being unhealthy food, work was my exercise, sleeping in the backseat of a Camry.
To be honest, it being there at 25 does worry me a lot. Is gynecomastia at this age something to worry about? A sign of worse things? I would also be glad to hear from other people who have had this condition after puberty but before the older ages when it becomes more common
