hi, my labia minora is swollen, after sex. It has been swollen for about 4 days now. It has no rash, just red, swollen, and like my innner lips are pertruding out. It does not burn when I pee, and I have had a uti before so I know its not that. Is there a cream I should use, over the counter, that will make the swelling go down? Or Cethaphil lotion?
