You should go again, and try again to show it to the gyno. Sorry, that's all I can suggest.

I had the same exact thing in the exact same spot. It's a cyst and you will have to get it surgically drained unless it breaks by itself. If it's what you have, be forewarned, it is extremely painful.

i had the same problem for 3 wks but gyno suggested to see urologist. after drinking cranberry juice 1 day (more if you need to), it burst on its own (blood and other liquids, scary at first and sharp pains but ok after 1 hour, somewhat fully drained). if not, i woulda been under the knife to drain it. i feel better now and bursting was a better case scenario. i obtained antibiotics for UTI and will see urologist for more details or any more treatment.
