Hi, I just read your post. I don't know if you still need help or not since this was a long time ago. My sister has some similar symptoms as you. She got a UTI and went for Antibiotics , but it didn't go away. She ended up taking several courses of Antibiotics and seeing every doc she could but it still would not go away. She found and herbal doctor who treats IC holistically. Her name is Matia Brizman and this is her website: http://www.icaroadtorecovery.com/
She helped to get my sis off Antibiotics and helped her to detox her body of yeast. Matia will work with you specifically to your needs and situation. It is a little expensive but totally worth it if you really want to get better. Besides that I can suggest doing a 2 month detox. This will be able to rid your body of all the toxins and bad stuff and allow your body to start to heal itself. I hope this helps.
