I can tell you what I have had done so far. Usually the first course is to eliminate all the other things it probably isn't. I had a CT scan to make sure I didn't have and ovarian tumors or cysts, or kidney blockages. Then I had a sonogram of my leg to make sure there was no deep vein thrombosis. Those would be the first things you would do. Usually a vascular specialist can helpyou determine if you have lymphedema. Barb
