Im going to offer some ideas, and I want you to google them so you can make an educated decision.
I worked in an herbfarm for years that taught alternative medicine and self-help.
UTI’s are pretty common complaints.
You do not have to take antibiotics for them when caught early, and even if its been a long time you can still treat but im way more concerned with your pain right now.
Many herbal “antibiotics” (more they are immune-supporters that also happen to kill bacteria) are also antifungals. This makes it tricky because if you have alot of candida, you may experience die-off in your treatment of your UTI. This would be herbs like echinacea and goldenseal. Astringent herbs like Uva Ursi kind of go in and tonify and “clean”.
Demulcents like marshmallow rt and cornsilk can help take the edge off the pain.
I have used GAIA’s Usnea/Uva Ursi Supreme back in the 90’s. It was excellent, and you can get it at any WholeFoods or healthstore. It specific for UTIs. Its as strong as any antibiotic,IMO, and doesnt encourage candida at all. Might even help eliminate it!
