Sometimes on the left, sometimes on the right
. I can feel a little ball on the right
all the time, when the pain
is there, it seems larger & it hurts. On the left there is also a ball, but when it doesn't hurt, I can't feel the ball. I have had a CT scan at the ER, they said they saw nothing wrong. I think I have a double hernia, (I do heavy work). I am female, have had all the usual, (Ovarian ultrasound, HIDA scan, etc..) Nothing. This pain is horrible when it comes on.
