I'm a 60 year old female. I have hashimoto thyroid. Other than that I have always been healthy until I took a hard fall on bathroom tile. A few weeks later (August 2009) I had a clavical blood clot. Took cumadin for 6 months. After that I was told that I no longer needed to take it because a blood test revealed that I was not prone to clots. Now I find a soft mass in the area of my clavical colar bone. I been having strange, discomfortable feelings along my arm, elbow, hand. It also hurts when I lift my arm or when at rest. Just wondering what it can be?
