Can herpes cause small bumps to appear all over the outer lips of the vagina or is this something else? had a yeast infection 2 weeks ago.

Maybe: With herpes, you may initially see a crop of small individual bumps that look like they have fluid in them, but they quickly spread and coalesce (group together). They also would go from itchy and irritating to painful in sensation. If you have even a small suspicion of herpes, then run - don't walk - to your medical provider or STD clinic for urgent evaluation and treatment. Hope that helps!
