I have had a lump over my outer right ankle bone for years. Recently, it has gotten larger and slightly painful, especially when I press on it. The area around my ankle and foot is also sometimes slightly numb and feels weak and tender. In the morning, the lump seems to be soft and squishy, almost like a half-filled water balloon. Later in the day and at night, after I've put weight on the ankle, it becomes "inflated" -- very large and more like a full water balloon. There's a small, squishy spot in the middle of the lump that I can feel and move around. I had been running up to fourteen miles at a time and first noticed more swelling than usual at that time. I've taken the past few weeks off from running, the lump seemed to be returning to its normal size, and then started to increase in size and get even larger. I've run marathons and half-marathons in the past with no problem.

I have also developed a hard, eraser-sized lump on my right ring finger; I don't know if the two problems are connected or not. I'm a 30-year-old female, am 5' 3" and weigh about 125 pounds. Thanks for your help.
