Wow. This is just fascinating. I use compression socks and elevation and have swelling well controlled. I lost 6 pounds the first week I started using compression socks. I noticed swelling in my arms also about the same time but it was determined not to be related to lymph. I had some episodes of swelling like this in the past in the legs, only occasionally every few years and it would pass. Last Spring this swelling kept happening daily and was very hard to make it stop. I also had a lot of foot and leg cramps at this time. From what I have been able to understand, that swelling in my arms that does not seem related to lymph can be related to nerves and "neuromuscular hyperexcitability." I noticed you used terms like these, and while I have some idea of what that means, I don't really understand it well. I have noticed the twitching can start within minutes of stress as I had a relative 95% remission of symptoms for a couple of weeks after relief of fears of it (clean neuro and EMG) and it started again intensely upon hearing some very bad news a few days ago. Your information here though, is the first I have seen where the twitching and lymphedema swelling might be related. Europe is far advanced from the US for lymphatics, the US does not have a single medical school with a specialty in this important body system! European medicals schools do. Doctors here are really ignorant about lymphatics. A chiropractor here theorized the swelling might cause the twitching. What I want to learn is if they are related, and if so, what might be causing both? Trying to figure out the swelling caused me great stress over the summer and then I noticed the twitching right after many studies and tests to determine the swelling was benign (but still so very rare and mysterious). So, if you could tell me what causes "stressed" guts and what might a food intolerance be? I do have a rather high fiber diet (psyllium husk) and always thought it was good for me. Maybe not? Feel free to Private Message me if you are more comfortable, or maybe this might be helpful to people in the future who search terms like "lymph." I had searched "lymphedema" on this site and nothing came up before. This is very, very valuable information to me. If I get to Germany I will take you for a wonderful dinner or something! Actually, I will be in Rostock/Varnemunde and Kiel in early July.
