One side of my labia majora is swollen and kind of numb. It just happened out of the blue today. I haven t had sex, there is no itch, no discharge, no pain other than its rather swollen. I had gallbladder surgery 6 days ago, and started wearing a cloth and velcro band around my tummy to apply pressure as I was really swollen in my tummy area and it was sore to just walk around. I ve been wearing it the past few hours and walking around, not sure if that could be the cause or not? I know my stomach has been rather swollen and lopsided ever since surgery. Ive never had that part of me swell before. Im 33 years old.
