I am a heart patient 78 yrs old. I am on a number of medications including blood thinners. I recently fell but did not bleed very much on my elbow. Three days later I developed a "pouch" on the elbow about the size of a walnut and started bleeding a lot. After three days I have stopped bleeding but the pouch is still there. It is soft and obviously filled with liquid. Probably blood. My question is whether or not this is a serious problem.
Thank You
