In 1968 I had 14 lynph nodes removed, and luckily did not have any swelling of my arm. But, recently the arm has swollen. In addition, I broke my left shoulder, and I notice the upper arm swells, but no pain, just difficulty with clothing, sleeve too small. The swelling comes and goes, and seems to be related to how much I use the arms. I am now 92, so the swelling may have some relationship to the medications I take. I had an aortic Valve replacement approximately 1 year ago. I find your article very informative. Thank you
