any nursing mama's have a sinus infection before? did the meds the Dr give you affect your supply? I feel like I've got one. so much pain in my sinuses and the left side blows out reddish brown mucus. I'm tired of this pain but I don't want my baby or my supply to be affected. I've already had to restore my supply once and it sucks!
