Suggest Remedy For Soreness In Head After Being Hit By Dog

Hi, may I answer your health queries right now ? Please type your query here... Just got back from a long trip and my 60lb puppy started running around the house. I bent over to pick something up and he plowed his head into my forehead full force. I fell back and since then have been dizzy every time I move my head. There is no lump but the spot he hit me is still really sore. It has been almost 24 hours and I am still dizzy. Will this pass or do Ineed to see a doctor?>
