One day last week when I woke up and went to pee it literally hurt my left side to pee and then when I went to work I had a hot flash and constantly had to pee. On top of that my belly button hurt to bend over and touch. And pain felt like it was spreading from it. Last night I noticed there was like brown crust in my belly button. But when I woke up this morning there was brownish liquid coming out of my belly button and white milky looking stuff in the inside. What is going on?
