so for the last few days I have had a strange soreness in my labia. Especially the left side... feel like when you've worked out & your mucles are achy or if you just have a really good bruise... well anyways, it hurts when I switch positions in bed, lift my leg, & sometimes wipe... I have the same soreness in my low abdomen & pelvis area when I breathe deeply, yawn, or cough... Can anyone explain what it is...??
