Feeling lightheaded and a little off after sparring?

i sparred two days this past week. 2 days ago was the last time. i really dont have a lot of experience with boxing and took a few shots that stunned me. i have been feeling lightheaded, kind of heavy on the left side of my head, when i move my head too fast i feel a delayed reaction kind of like the inside of my head has to catch up. anybody ever feel these symptoms after sparring?
