I am 66 years old and had to have my ovaries taken out due to large cysts 3 months ago. Uterus was taken out 15 years ago. I am very dry and get yeast infections. I saw a nurse practitioner and she did a culture and said there was no yeast or bacterial infection. I just burn badly. She gave me some cholestryamine 5% with aquaphor cream to apply 3 times daily. Now this is my concern. She pescribed boric acid 600 gm capsules to use 2 or 3 times weekly to prevent yeast and help balance ph level. I can not use creams for yeast because they burn me and so I only take diflucan pills. I am so raw and inflamed I'm scared to use the boric acid capsules. Guess I'm a little paranoid because of all times I have been burned from creams and now red with inflammation. Has anyone used the boric acid capsules and if so have they ever caused you to burn? Any advice will be so appreciated.
