There are very good & effective homoeopathic medicines for recurrent UTI and overactive bladder, but you need to give a proper case history and take a constitutional medicine instead of a specific medicine.
Next Steps
You can consult me online on Practo to discuss the case history including mental health problems/stress (if any). I will presrcibe you a proper medicine according to your constitution.
Health Tips
Maintain personal hygiene properly. Wear fresh, clean undergarments everyday. Have 2 to 3 litres of water in a day. Do not delay the urge for urine. Avoid using public toilets.
