A few months ago I was treated with antibiotics for a urinary tract infection. Since then my urine has always been of a really dark brown colour. It does not hurt. My partner is the same. I have taken an STI test and it showed up nothing. I drink lots of water so it can't be dehydration. Just recently I have also noticed that even if I flush the toilet a few hours later the clean water turns to the same colour as my urine.
Could you please advise?
Kay.
