It’s normal to have bumps on your nipples that look like pimples but don’t necessarily feel sore like pimples. Do the bumps you’re describing kind of look like Braille – the reading system for blind people – on your nipples? I know, weird way to put it, but when thinking about how I was going to go about explaining what the bumps on nipples look like, Braille was the first thing to come to mind.
If the bumps on your nipples are sore and somewhat painful, I’d suggest seeing a health professional. But if they’re simply just little bumps on your nipples that don’t do much other than just sit there, then there’s nothing to worry about – It’s absolutely normal.
