It never grew big enough to pop by the way.
Well, that's annoying! Did you have a doctor diagnose the cyst and monitor it?
So, next time when at the doctor, show them. Do you get regular ob/gyn appointments? Every woman should have a pap smear once a year. So, that is a great time to get medical examination of it. It is probably still there but has changed as a B cyst can often just be a lump.
What you can do now are a few things to see if it helps. Dab tree tea oil on it (can get almost anywhere these days but definitely at health food stores), try a sitz bath (fill tub with warm water about 3 inches and soak for a bit), take a probiotic (pill form or drink one of the smoothies daily--- this will help lots of things unrelated to this like digestive health, etc.), you can try dabbing apple cider vinegar on it with a cotton swab. Those are just some home remedy ideas to try.
But I'd get it checked. Does it bother you other than just being there?
