Hi, I'm a 15 year old girl who has been experiencing some weird discharge from my belly button. It started 2 days ago, I felt a sharp pain right above my belly button but immediately ignored it because it lasted for only a second. I felt it again once more a few hours later but once again, it only lasted a second. When I went to take a shower that night, I realized the area around my belly button was crusty, and I had a brown, sticky, and foul smelling discharge from my belly button. It's texture (and color) was the same as ear wax. I've read on some sites that sweat and dirt could cause a bacterial infection. I do live in a hot area with no AC. I was really confused and I confronted my mom about it and she said it's happened to her about 3 times and to put (rubbing) alcohol on it and it should go away. If it helps, I think I'm getting my period soon. I've never experienced this before and quite frankly, I'm a bit nervous. So my question is, how likely is it to be something of concern (a cyst, internal problems, etc) and how long should I wait before I go to my doctor? Thank you in advance.
