Were you tested for STDs/STIs like herpes or do you think you may have an allergy to a new soap/body wash/laundry detergent? Have you started any new medications or bought new underwear that may be irritating your genitals? It sounds like something touching your genitalia is causing your symptoms. Do you have a new partner and could they have exposed you to something new? I wonder if some tests may not pick up something new depending on the infection. You may want your gynecologist to do testing again. You also may want your primary doctor to do other bloodwork to see if anything shows up being off balance.
