Last week I recently notices one only pea sized sore that is red and kind of looks like blister but is more under the skin causing a bump but contains no puss and is on the outside my vagina, I m very worried it could be herpes because every time I try to look on line about it I get the result of herpes I showed it to my mother and she told me not to worry unless more show up but now that I am worried about herpes I feel like I am analyzing every tiny bump!just wondering if it sounds like a herpe blister?!
