i should be fine after this right?

at work there's the big 5 gallon jugs of water. i was getting more from in back to restock them. while i was grabbing one off the shelf, the 5 gallon jug of water tilted too far and hit my ear. major ouch!! once it stopped hurting i felt fine. my hearing has been normal, no vision changes, not even a headache. the top of my ear is sensitive to pressure though. but i figure just don't push on it. i'm tired but thats normal after an 8 hour day at work. i mean if i had a concussion i would feel weird right? cause again i feel fine just getting tired like normal.
