strong different smell to urine

ocassionally the last six months my urine has a strong odor almost like sulfur

I know it's been a while since you posted this, but did you ever figure it out. my doctor is stumped. no UTI, just urine odor and sometimes upper vag pain.

Did you find out what causes this smell, and about your pain, I have similiar symptoms....

Strong urine smell can be caused by medications and diet. The strong sulfur smell is generally caused by foods containing thiol and/or mercaptan compounds, which contain sulfur.

Some of these foods are onions, garlic, asparagus, and cabbage.

I was wondering if it was possible that multivitamins could cause the sulfur smell in urine? I have noticed over the past few months that, at times, my urine has a very very strong sulfur odor to it. I should mention that I am 26, male and have had prostatitis and take cardura and avodart regularly for that issue. I was starting to get concerned that maybe it was something really really serious since some had mentioned it being urinary stones and such, but then I remembered that I have recently started taking multivitamins, one in fact, is a B COMPLEX that STINKS like rotting eggs. I am wondering if that smelly pill is just flushing out through my urine and causing the odor? is this a possibility?
