Hello. I'm looking for help on how to treat this issue I have been having for nearly a month now.

I have been having an itching feeling around my scrotum. It started happening after I was cleaning my behind of diarrhea. It started out itching like crazy, which I assume was because of a rash. But whenever I had to poop, it came out as diarrhea and was sometimes hot, and hardly any came out. I assume it was constipation so I took mineral water but it didn't help. Over the ourselves of the last weeks it's been getting better and better each day. My butt has been getting cleaner and way less itchy.

But here is why I'm asking for help. Recently I had a stomach ache that I never had during this period. I went to the restroom and had diarrhea but it was a normal kind. I had it twice the same day and afterwards I felt so relieved. My butt felt completely normal. But a day later it went back to a slight itch again and my poop wasn't coming out normally again! : (

Please, I ask for any help. I don't want to end up having a form of cancer or anything. I'm only 16 years old! : (
