Mommy’s please

Breastfeeding moms. I think I have a clogged milk duct. I do massage it even tho it’s tender and I have been breastfeeding with it too but I have a fever and I don’t feel like eating and my head hurts and I feel cold. Anyone know why and have any suggestions? Oh I don’t know if this is related but My backs hurts like my kidneys and I also can’t really hold my pee in and my head doesn’t feel so good.
