Got hit in the head with dodgeball, no concussion symptoms am i going to be okay?

Significant issues related to head trauma are usually evident at the time or within hours. Lack of neurologic changes, dizziness, balance problems, etc. suggest no likely long term problems will be seen. Headaches of variable intensity can appear in the week following such an event & are not by themselves, a worrisome sign.

Virtually all humans suffer relatively minor closed-head injuries during their lifetimes, and very few develop catastrophic consequences. Dr. Ferguson summarizes issues quite well. Not clear from your post as to why you are so concerned.

A dodge ball is not as hard as a baseball, golf ball or other sports balls. The intensity of the blow and the hardness of the ball will determine the after effects. No dizziness, or fainting, lack of motion and any other abnormal results, than you are fine. Rest up for a hour and play again. If so concerned, wear a helmet next time.
