Hi, I am breastfeeding my 2 week old dd and developed a very sore breast yesterday evening. Last night I was achy and shivery and felt miserable so I suspected mastitis. I took my temperature and it was normal so I took paracetamol and went to bed with a hot water bottle. I felt better this morning although the breast is still very sore but went through a bad patch this afternoon where I was shaky and headachy. Still no temperature though. Does it sound like it could be mastitis? The breast is very tender and there is a little lump (blocked duct??) but I am feeding from that side and it hasn't got any worse.
