Make sure to check your blood pressure. Call your OB, they might have you come in for a check up. Might be nothing but, in my case, I've had a terrible migraine for a whole day and got diagnozed with preeclampsia the next day.
Staying well hydrated helped me. 60+ ounces of water a day.
Magnesium and vitamin B-12.
Definitely check in with doctor.
Sounds like migraines... Ice packs?
Stay hydrated, check your blood pressure, get some low-impact exercise (like walking), avoid caffeine and sugar.
