Shame on them!! Good luck...garlic is very good for everything. Also you can try to take some probiotics. This might help if you have a vaginal infection. If you suspect a yeast infection you can try monistat too. I hope everything works out for you. My mom once told me that she heard that alka-seltzer can help a UTI as well.
Coconut oil is also very anti-bacterial and anti-fungal. If you can get your hands on some I would highly suggest to start taking it daily. But start slow, maybe 1/2-1 tsp a day till you can work up to 3 tbsp.
