I am a 42 year old male. Recently, within the past six months, I have had periodically very, I mean VERY strong urine smell when I urinate (on occassion after intercourse with my wife). So strong, I have to hold my breath when I go to the bathroom. It smells, to the best of my description, like strong medicine that's gone bad. I'm not taking any medicine aside from my HBP medicine that I've taken for 17 yrs. The only other symptom I have are that I've had frequent bouts with groin pulls during the same period, and I have mild headache and nasea when the smell is really bad. Also, at times I sweat while sleeping and I can smell the same smell although it is much milder than when I urinate. Again, it comes and goes, but is VERY , VERY strong right now - almost unbearable.
