ROFL! When I had it I couldn't feel any lump at all, but it was definitely mastitis. Just makes it easier if you can figure out where the blockage is, that's all. I had the red sore area though, ouchies. It hit me really hard, I was flat on my back 30 minutes after first feeling unwell. But 24 hours after starting ABs I was heaps better. Good luck babe!!!
