headache after giving birth

I had my baby 4/11 2:29pm I had an epidural and yesterday I started getting a headache after breastfeeding and pumping.. today I pumped and I got it again it was HORRIBLE throbbing pain. I had to stop pumping. I told my doc and they told me to lay down if it stopped while laying flat then it could be a leakage from the epidural.. we set up to do a procedure 2mm morning to patch up the "leakage"... I haven't slept normal most like 6 hours and I've also been stressing breastfeeding and adjusting to our baby.. idk what this is anymore if it's a leakage or just sleep deprivation headache /: has anyone had a leakage before from the epidural? How does it feel and how did they treat it and did it go away?
