@pilgreenheather, let them know as soon as possible. It could be spinal fluid leakage. I had THE WORST headaches for days and ended up back in the hospital because of that. It's awful.
Let your doctor know could be a headache from the epidural. Let them know asap they can help you out but don't let it get worse without saying anything. You could also go to the ER.
@justusthree, yes I pushed for 3 hours and had to have a csection cause her heart rate started dropping. And they gave me more medicine through the iv in my back before I went back for the csection
