So, last night me and my boyfriend were laid in bed playfighting, he were throwing his fist towards me and I was blocking it. But just my luck, I moved my arm thinking he wouldn't carry on but he punched me in the forehead quite hard. His knuckle got me slightly higher than the middle of my eyebrows, I now have a lump that is starting to bruise and really sore to touch and have had a headache since. I have also been red and blotchy all across my forehead. Is this normal?
