I think I may have this too. IC .Because my urine tests clear from bacteria also. Feels like a uti, but it just burns. what do you think? do you think its possible i may have got this from the sulfa antibiotic? thats when this all started on me. Were you on any recent anti biotics or anything like that? I ended up in the ER from the sulfa, and its been everything fron this, to yeast since. cindy
