Oh yes, I get them often. Whenever I have IVs, and also occasionally bc of oral abx. For me, the zithro doesn't cause a raging one, but it will definitely cause an increase in yeast.
I would rule out bac vaginosis too, just make sure your gyn saw it, and knows for sure that it is yeast.
I've done medicated treatment for yeast before for the really bad infections. But usually, taking lots of probiotic daily will help keep it at bay.
Yeast easily accumulates vaginally which is easy to tell, but if its there its probably also in your intestines which isn't good. Taking probiotics daily helps with it.
I wish docs would tell us this stuff before we take the abx, bc it could be prevented. But its one of those things that they just seem to wait until its a problem and then deal with it.
Until you get treatment, a warm clean washcloth can help with the discomfort.
