Hello im a 19 year old male. I see a lot if replies mention a painful experience but mines does not hurt. Unfortunately it feels harder than a mere pimple which makes me more afraid. I'm not sure exactly how long but I had it for at least 4 years. Over time my doctor said I was healthy so I ignored the lump. The lump size did not significantly increase over time so I'm not sure if it's serious. Embarrassing or not I'm checking this with my doctor just to be sure. I just wanted to share my experience.
