I have several lumps under the skin on my inner thigh, they burn and very painful to walk, and sleep threw out the night. I did have blood clots in the past, and I m worried, should I be, What should I do. I went to a doctor and was told its from vertical veins, but I received no answer on what to do. Please help? I also have a Factor 5 blood disorder, that I found out five years ago.
