J.,
Do you have a fever and have any flu like symptons? If so you may have mastitis. It is a infection that requires an antibiotic. Don't woryy, you can still bf and take the medication. Actually bf helps get you through it. I use to get hard,tender places in my breast too. It was a clogged duct. Just keep nursing and take some Tylenol if it is painfully. They usually lasted a few days for me. I would get them often. My two girls also nurse constantly and i was never engoged. so i guess it is common. I hope this helps
