I hear you. I live in the tropics so you can imagine my response to the wearing of garments in the heat. I am lucky and can often wear a custom made one that goes to my elbow. There are times when I have to wear the long, but have two piece. Here is my tip. Get yourself some Hercules tough trial nitrile disposable gloves , or similar, gloves are blue, very flexible and a bit bigger so will slip over your gloves. I get them in Woolies. I have one permanently by my kitchen sink, one in bathroom etc. I wear them over my glove when cooking, washing up etc. can wash your hands (well the other one that got dirty) in them. They are a godsend and not nearly as heavy as rubber gloves. I reuse them in the kitchen.
It is nice to see lymphedema being discussed on here. It is often the forgotten side effect of this rotten diseas and one that nearly tipped me over the edge. Hang in there it does get better.
