hi Several times a year I get episodes of very strong amonia odor and its pretty disgusting,I have been checked for infections but never have any , I do drink alot of water so I do not feel its to strong of a urine problem, also at other times I have another awful odor that is like sulphur, again no infections are present, how ever I am always so self consious of myself and hope no one else notices, this is all very embarrassing and there are times where I will go through many pairs of underwear, honestly it seems like something is so strong that it is making holes in the crotch of my underwear, any one else ever have this??????
