Debilitating round ligament pain

Has anyone found a good way to get relief from severe constant RLP? I can't hardly walk to the bathroom without stabbing pain with each step. The only other thing my Dr recommended was physical therapy, but I was wondering if anyone had done that and found some exercises that worked. I try to keep stretching as much as I can and I've got a support belt I wear constantly, but no luck. We're leaving for vacation on Friday and I'm afraid I'm not going to be able to make it through the airport. I NEED this baby moon!! Haha
