One night I woke up, then suddenly I noticed my skinhead red with irritation. Afterwards, I went to pee and it did hurt from the inside. Later, that same day I went to work and after maybe 2 hours I began to feel dizzy and I got a bad headache. Finally, the next morning I began to pee blood for the first time in my life. I don't know what has caused this or what is what I have.
