I developed Lymphadema this past March. I had cancer, breast, 25 years ago. I had a lumpectomy, chemo and radiation treatments. Never had trouble with my right arm or any sign of Lymphedema. I injured my hand in March and it activated secondary Lymphedema in my right arm. I have, and am, having therapy. In the past few days I have had shaking in my right hand! It scares me. Why? It just started. I noticed it when I placed a coffee cup down and I had a time controlling the shaking. It has continued. Please advise me what is happening and what should I do?
