You suffer from recurrent UTI because the flora balance is damaged by antibiotics. I'd like to recommend 3 months medication with Diuretic and Anti-inflammatory Pill for treating your condition.
As this is a herbal medicine, it boosts your immunity as well as treating your infection. Unlike antibiotics, it won't bring you flora imbalance. And it can preserve your body while treating your disease. As it's a natural treatment, it has no side effect.
