I feel flu-ish, it happens very quickly...I get really cold and achy, have to go to bed and wait for ot to *break*. I usually feel much better the next day. This has happened to me twice in the last 2 weeks. One day a week I work 6 hours, dd(9m) goes with me and ds(4) goes to preschool. After I pick him up he goes straight to Karate. I always end up engorged. It's about 9 hours that ds doesn't nurse and with all of the running around the baby doesn't nurse as much. Could this be what's causing this to happen? Is it a plugged duct? It happened last night, I'm better today but my breast is still sore and I have a headache. Maybe I should start pumping at work??? ugh!
