Blood patch

Hey you guys I just had a blood patch after having a rough delivery after c section… has anyone else had a blood patch? It’s extremely sore but I’m so scared to even cough or bend my neck as it hurts severely bad.. I keep telling nurses my headache did go away but for some reason now I feel throbbing in my head like it’s trying to come back? Is this normal? Please gimmie some advice on what to expect, I have spoke with dr they say everyone is different so they can’t tell me much
