Did you spend some prolonged time on your knees? Maybe you and your partner just couldn’t wait to make it to the bed? For whatever reason, you were rubbing some part of your body on the rough rug (or bamboo bathroom mats) for a while, and now you have rug burn!
What to do
If it is just a little rug burn, putting ice on the area will calm it down, and it will heal quickly. If you got scratched up and there’s blood, apply an antiseptic right away. Think about it: you have an open wound, and you were repetitively rubbing it on one of the dirtiest parts of the house.
