I’ve had these three cuts on my legs that have been inflamed for over 5 months now. They itch sometimes, but I can’t tell my parents and they are turning purple. How do I get rid of this?

I would recommend going to your gp or to a doctor. They are most likely infected and could cause seriously damage towards you can your health. I know it can be hard but it's important to tell someone, more importantly an adult, such as a grandparent, aunt or uncle or trusted adult. I've personally dealt with self harm and infections and they aren't good. I didn't tell my grandparents about a seriously infected cut because i was scared of being shouted at and i nearly had my leg amputated because of it. Though I didn't get shouted at, sometimes fear can make us keep in secrets and things despite us needing to tell people thing
