I highly recommend taking is EASY for a few weeks at least. Do lots of walking though if it doesn't give you any symptoms.

I'm a year out from a similar minor concussion from boxing. I went back to practice a few weeks later and took the slightest bumps/hits to the head, and its made everything way worse.
I still can't run.
Why don't you try riding the stationary bike for awhile first, and slightly build up how long you ride and how high you raise your heart rate? That's a much safer bet than just going for a run cold turkey.

I recommend seeing a physical therapist or sports medicine doctor - someone who can help guide you back to exercise and monitor your progress.

Best of luck
