have you been tested for herpes simplex? sometimes if you don't specifically asked for certain test they won't perform them. you also may be experiencing an allergic reaction to the soap you use or you may be allergic to cotton panties or the detergent you use to wash your clothes. it may be something that you may have no idea how to find out if your allergic to in that case an allergy test is needed. talk to your ob/gyn.
shiny red sores on outer labia (line running from top to bottom) had for 3 years - now 17 yrs old. had the sore area for 3-4 years now (ever since i started my periods) - i take microgynon 30 (have done for 2 years) and have been checked for std's (none). i have a shiny red line on each side of my outer labias that run from the top to the bottom and it's is very tender. sometimes i get cuts ans splits in the areas which become extremely sore. whenever i go swimming i come up with a very sore rash that looks like burns. i have eczema cream for mild eczema on my legs and stomach.
