Morning @Shellshocked2018_
I had up and down swelling for ages. The more work I did during the day, the more swollen and hot at night. In saying that though the more you can do with your arm the more it helps I believe. I found that where the wire sat made a big difference. If you can get a bra that the side wire sits a bit lower it seemed to help a lot.
Berlei makes a bra called the "Brazillian". The wire and side support doesn't come up as high as some of the others, it's lightly padded so very comfy and pretty. Very supportive. Even holds the bounce while horse riding :) I've had no issues with lymphodema and do a lot of physical work.
