The number one rule to prevent any pain is to choose the right size of bra for yourself. Unfortunately, many women face various issues with their bras because they don’t wear the right size suited for them. Even if you have the right size, you might have sensitive nipples. And if you’re an active person, they might be causing pain to your nipples. So try to use pasties, silicone covers, tapes, and other such nipple protectors to provide relief to your sensitive nipples.
