Ultimately, you need an evaluation to understand the cause of your pain (exam, maybe labs and ultrasound).
But just a comment about abdominal pain radiating down the leg.
The uterus has a ligament called the round ligament. It starts at the shoulder of the uterus on the right and left side near the connections between the fallopian tube and the uterus.
The round ligament then travels into the inguinal canal which is a narrow tunnel on the inside of the right and left sides of the pubic bone. The ligament travels through this canal and ends inside the right and left labia majora of the vulva.
Processes involving the uterus such as severe menstrual cramps, a growing uterus in pregnancy, and large uterus such as from fibroid pulls on the round ligament . This pulling can give pain in the labia but also down the legs.
if you go to Google, there are some comments about it. Here is a link to pictures.
I have been experiancing some awfully sharp pains down the right hand side of my stomach which can travel down my right leg to my knee, some times these pains are so bad it brings me to tears and I can hardly move. I dont have it all the time it normally comes in waves. couldd this be an overian cyst?
you should see another gynecologist if you feel you are not being listened to. I wonder if you have endometriosis. Going on the pill is the right intervention but sometimes doing a laparoscopy to confirm the diagnosis is an other approach.
Usually we try the pill for 3 to 6 months first
