I know this hamsap uncle go massad center "pull nerve" then kena yeast infection. The thingie got tiny red spots on the tip area and very itchy. He used apple cider vinegar, garlic, yogurt all no use, then when doctor gave wide spectrum antibiotic, become ok.

Because the antibiotic too strong, it also kills good bacteria and he got diarrhea for the duration of the antibiotic treatment
