Was your heart rate 85-90 before the hit? 85-90 is still normal.
Did you have any medical test for the head? A concussion needs lab tests or imaging tests to confirm. Symptoms of concussion include pressure in the head, headache, confussion, dizziness, if you feel fine, just take a good rest. There's no better way than rest for concussion anyway.
However watch out these symptoms, and let your family members know about these, if any of them occur, it means the injury to the brain is more than a concussion and you'll need to be sent to ER right away.
