I was trying too avoid my dog getting in the house cause it will shit everywhere, so in a moment of sheer angst, i yanked the door open quickly so i could pop inside without my dog getting in. Well, when i yanked it open at full force almost, my head (Eyebrow area) just so happened to be in the way..It struck me..hard. I walked inside grabbing my eye. The pain was very intense. After aboiut a minute that worst subsided, but i am left with a burning/achey feeling just above my eyebrow and a pea sized lump aswell. Anyone think this is enough too cause a concussion??
