Hi, I am a 43 year old male who for the past year has been having an increasing stronger odor of fish, or rotten fish in my urine. It doesn't burn when I pee, although I would say that after a long night of sleep where I haven't gotten up to the go to the bathroom, when I wake up and pee it burns for like the first second and then goes away......but my pee, first thing in the morning is very dirty brown and smells the worst in the morning after I haven't urinated all night. I was in a committed relationship for about 3 and a half years and it ended in February of this year. I was having these symptoms shortly before we broke up and it has just been getting worse throughout the year. Obviously, I am wondering if my girlfriend cheated on me shortly before we broke up and I contracted a sexually transmitted disease. Thoughts?
