Concussion from walking into a door....?

fe

So as I was leaving from putting my daughter down for a nap, somehow I managed to hit my head so hard on the door, I immediately saw stars and blacked out for a few seconds. I played it cool so she wouldn’t freak out, then I shut the door and I got so dizzy I couldn’t stand up, I couldn’t move, my ears started to ring and I felt my heartbeat in my throat, it felt like I was going to throw up and faint at the same time, my vision was blurry and fading in and out. I also started profusely sweating and now I have the chills.

It’s been about 25 minutes and I no longer feel extremely dizzy or nauseous, but I still have the chills and feel exhausted and obviously the bump hurts.... should I see the walk-in clinic?? Or just rest? I mean if it is a concussion it’s not like they can do much anyway. Idk. It was really scary. I have never hit my head that hard before in my life, I have never experienced anything like this...so I’m not sure what to do.
