Sounds like you could have a secondary infection, however, it is difficult to say what "exactly" these "bumps" are.
Follow this up with your physician; the physician who prescribed the cream for your yeast infection.
Refrain from sex until this is resolved.
Keep us posted.
I am not a doctor I am a microbiologist. But I can give you some advice. You could have some other type of infection. It sounds like a urinary tract infection. It may be a bacterial infection on the bumps as well. I would go in and see your doctor to have them test you to see if you have a urinary tract infection. Since it is Friday. If you are not diabetic you can drink a lot of cranberry juice and water and see if you feel better by Monday. If you don't go into the doctor. For the spots on the external vagina I wouldn't put anything on them and leave them alone. Don't scratch them or anything. See if they go away on their own. If you get a high fever or feel much worse you can go into your on call doctor on the weekend or urgent care. Of course if you want to talk to one of our doctors and pay the fee you can or call one of the online doctors you can get on your computer so they can chat with you that is another option. But, I do think it sounds like a urinary tract infection plus the bumps need to be checked out. They will do some tests on the urine and possibly a culture as well to see if it is a bacterial infection of the urinary tract. I would probably stay away from sex until you clear the infection and see your doctor. It will irritate the problem.
