Head injury from a horse fall?? Concussion?

I had a pretty bad fall today. I know compared to people who had their ribs kicked in and nerves pinched an what not will think this isn't a bad fall. My horse tripped and fell forward and i hit my head on the ground and skidded on the dirt. Thank god i had a helmet but now it's 8 hours later and my head is starting to throb and i feel very dizzy. I wasn't dizzy until about an hour ago. I also busted my chin, lip and jaw. Do i have a concussion?? Should i see a doctor if i still have a headache tomorrow??
