A persistent UTI with E.coli, pain, and weight loss suggests chronic infection possibly aggravated by the 3 mm
kidney stone. The stone may be acting as a nidus (root cause) for recurring infection. While Ayurvedic medicines like Gokshura, Chandraprabha Vati, and Punarnavasava are helpful, long-term infection requires deeper detox and Rasayana therapy to strengthen immunity and urinary health.
I strongly recommend an in-person Ayurvedic consultation for integrated management, including mutravirechana, basti, and targeted herbal combinations.
