R eats only one side at a time and last night did a 7 hour stretch (!!!) I was engorged on both sides at different times but now I feel deep bruising in one armpit. I just fed him and then pumped that side while massaging the bruised area. There's no lump though. Could it still be a plugged duct? My toddler has a cold and I suppose it could just he a lymph node from fighting whatever he has?
