What are the signs of an infection? I have three cuts, done at the same time using a clean instrument and cared for appropriately afterwards, and they are oozing pus a little. I'm guessing this is a sign of infection? But there is no redness and no pain ( no more pain than could be expected for a cut). I've been keeping them covered up but I'm not sure what else I'm supposed to do. Is putting strong antiseptic liquid on them doing more harm than good? Am I supposed to keep them covered all the time? Such is my pitiful knowledge of first aid, lol. Advice, please.
