For about 2 months I have had a grape sized lump under the skin, on the back of my thigh (it feels like it is attached deep in the muscle). Looking at my leg, you cannot tell it is there, and doesn t hurt unless pushed on. Over about the last week, the lump has swollen, hurts all the time, and the area around it is now purple/red. Additionally, I have 2 swollen vericose veins right under it. I don t know if one has to do with the other? Could it be a blood clot? Do I need to rush to the emergency room? Any advice you can give will be helpful. Thanks! Dana
