Am I reading your post correct if I say that you have been operated 4 times (2 times on the left side and 2 times on the right) or is it only one time per side?
Have you emailed Dr. UM about your new problem?
It can be so simple that you fascia around your leg that goes up deep inside of your leg is very very tight beacause it has have to compensate for your weak groins. If that is the case I am sure there are people here on this board who have suggestion on how to "loosen up does fascias"
When you decided to go to Dr. UM for the first time was it beacause of this thread and the info here?
