Do I Need To Worry About A Concussion After An Injury At My Eyebrow For Which I Have Taken Ibuprofen Thrice?

I am a healthy 70 year old male. I was working on refurbishing my hanger at the local airport. A guard rail from a scaffolding fell on my head and made a cut by my eyebrow 2 hours ago. I put ice on the wound and took 3 ibuprofen. There is slight swelling. Do I need to worry about a concussion? Should I go to emergency?
