Vaginal and anal burning

I was one day away from finishing amoxicillin for intestinal inflammation and this burning came over my vaginal and anal area.  I am a stone former and my urine pH has been very low, so I thought that might be it.  There's no itching but my labia are swollen and it almost feels like a reaction to a new detergent.  I thought, after reading above that I should try the suppositories.  The day after the anitbio was finished, I started eating yogurt but I was hoping for something topical that is natural.  Any suggestions?  Someone mentioned a boric acid wash but didn't give the measured amounts.

Try using a Canesten vaginal pessary. Sounds like you have Thrush. Caused by the Amoxicillin.

Some ladies find that live plain yoghurt put in the vagina helps to stop it,but it must be live.
