I agree concusion comes with all those feelings kane said,you hit your head it will hurt if the headaches do continue see a doctor.
Hello, Im almost 100% certain that it wouldnt be a concussion. Even though the back of the head is the worst spot you can get hit or fall on, you would still be having tremedous pain along with other symptoms like dizzyness, blurryness, tiredness. Im sure you just had a bit of a headache for awhile. Take care
