2 days ago, I was playing football in my backyard and rustled my head pretty bad. I didn't hit my head, but I jostled it pretty violently.
I've had a minor on and off head ache over the last 2 days. I had nausea yesterday, but it's gone away today.
No mental/cognitive problems. Just the headache. Should I visit the ER or am I safe to wait until Monday to make an appointment?
