What can i do if my boobs get hard and sore when i take my bra off at night, should i be worried?

See dr if concerned: Some women (especially those with larger breasts or who are pregnant) sleep in a bra for comfort. It is recommended that a bra worn for sleep have a soft cup without underwire or metal clasps. A shelf or cross-over design is also recommended. Bras worn for sleep are made. Use of improper cup depth can lead to rashes or chafing (due to breast contact against chest wall w trapped sweat).
