You'd think I'd know this by now...

On from last week, my right breast now is in pain. This time though it has progressed to a large lump on the underside, inflamed and red. I also have a bad headache and aches, but no fever.

Does this mean it is only a blocked duct and not mastitis? Is the fever the key with mastitis?

As per normal when I start to get mastitis I feel like I've been hit by a truck, just lacking the high temp.

Do I treat a blocked duct any different than mastitis?

Oh and as a vent *woe is me*
