Hi, I Am A 24 Year Old Female. I Don't

Hi, I am a 24 year old female. I don't smoke and I work in healthcare so I lead a pretty active lifestyle (on my feet working 8-10 hr/day)

I recently noticed a dime sized knot on the medial side of my calf, about 2 inches below my knee. It is sensitive to touch, but not visibly inflammed. I was curious and took an LED light to the surrounding area. I can trace my veins with the light. I can see a large bundle/clot in the spot, along with a smaller clot about 1/2 inch above it. Could this be a blood clot? My foot does seem to fall asleep quickly and often....
