Please help! I think I may have pin worms but I'm not sure.the thing is it might be puberty because I am 14 and itching and my already big appetite got bigger and year or so ago. My stomach started vibrating and growling alot during school and before it never did this a year or so ago.also the itching has stopped months ago around the anus area but now it's fine. We had changed out toilet paper around the time it started.please I need answers!!!
