Headache after piercing!?

So I just got my conch piercing done today and I didn’t think it was that painful at that time but after a while it started to hurt a bit and yeah I understand that it should. But here’s the thing right, I started having a massive headache right after the piercing on the back of my head (the left side on which I got the piercing to be precise)and it’s started spreading ? Like idk if I’m being paranoid or something, I need to know if this has happened to someone before.
