My second lymphedema flare-up in two months is back under control through bandaging. Although I hate wrapping (it feels like my entire arm is encased in a huge, tight oven mitt), it really works. Bandaging for a couple of days, self-massage, and drinking some homemade oxymel seemed to do the trick.
An on-line friend who also has lymphedema told me about oxymel. It's a medieval recipe for "what ails you." Combine 4 ounces of honey with hot water and vinegar in equal parts. Add 1 ounce fresh rosemary. Steep in a coffee maker for several hours. Drink daily diluted with water or seltzer.
