Im not prone to UTI.s. Last week after 2 very stressful days and hardly any sleep went to loo when i got up, all felt normal but about 5 seconds afterwards was this awful Sulpherous odour ..I first thought was something down loo, but its used by two people and was only me it happened to. No other symptoms.. I hadnt eaten anything different that would cause it either. It happened exact same next 2 days. Had an E Consult with GP..As urine colour had varied thrrough day from normal to darker yellow he said could be UTI or Dehydration. Gave me the most awful side effect Anti bios..and told to drink more water... Has anyone else had this sulpherous odour ?
