a little over a month ago, i whacked my shin pretty hard on some iron gym equipment. for 3 weeks, it was painful to walk on that leg, and i had a huge egg shaped bruise. the bruise began to fade to a yellow-brown but stopped healing after that and i have this 'shadow' where the purple bruise was. i started freaking out and thinking it was leukemia since it seems to not be healing anymore so i asked my mom if she thought this meant i had leukemia and she told me if that were the case, i would have other symptoms and my other bruises wouldn't have healed, and they did. she thinks im freaking out over nothing and that i bruised my shin bone and it will take a while to heal. what do you think? is this leukemia or just a bone bruise taking its time?
