no head lice does not leave bumps or bruising but depending on how often they bite you an area it can become sore. if you are worried about lice there is a place in tigard and beaverton i believe called lice knowing you that check and treat for lice. if it is something you cannot afford at least do buy lice comb from there because their combs are 99% more effective than drug store combs. you can still buy one from the drug store and if you do not have olive oil or coconut oil buy some and some plastic shower caps. after that go home and apply alive oil to everyone's hair make sure you get it everywhere then put the caps on and either sleep with the olive oil on and wash it off i'm the morning or just put the blow dryer over your head for thirty minutes. before you wash out the olive oil though get everyone's laundry in the laundry room put stuffed animals in large garbage bags for three weeks or just toss them in the dryer for thirty minutes on high and vacuum everything.
