My Clitoris Hurts So Bad!

Okay this may be a little TMI but I am in desperate need for advice. So after I had my first child my vagina would not get wet at all when my husband and I tried to have sex so we would have to use lube, well sometimes it wouldn't be enough and after sex my clitoris would be stinging and burning! It only happened a couple of times right after I had her. But all weekend my clit has been hurting so bad!! I haven't had sex as hubby is away so I have no idea what I could have done to it to make it hurt so bad! It is swollen and feels kinda hard! Pleas someone help I can't even stand or walk for long periods of time!
