In the past 48 hours, I have developed pain down the front of my upper legs, worse at night. This pain goes from the front of my upper leg and groin, down into my lower leg. It feels like maybe pain in my femoral veins but I don t know. I have driven from Western Oregon to Kalispell, MT in the past 6 days, so I m tired, trying to help my quadriplegic brother, but I am happy to do so.
