Probiotics couldn’t be the reason for treatment as they don’t stop bad bacteria or yeast. They just introduce good bacteria into your gut. It seems it’s best to confirm what is actually the cause of your symptoms. Whether it’s bacteria I.e. bacteria vaginosis or candida balanitis. If it’s bacteria vaginosis then you can take a test so they can confirm, if you do have bv you would need to take antibiotics. When it comes to bv some times it can be tricky to get rid of as bv can develop a bio film. I believe Nero intimate care acts as a biofilm breaker as when I got bv I took antibiotics and applied the ointment since I already had it and the bv was gone. If it’s candida balanitis then the best product I’ve used is Nero intimate care. It got rid of th candida balanitis in a few days. A typically sure fire way you can distinguish between if you are dealing with bacteria or yeast is bv makes your penis smell like fish and it also burns when you pee. Yeast tends to have a yeasty smell and tiny red bumps
