Abdominal fluid retention

My lymphedema is the result of cancer treatment and steroid use due to adrenal insufficiency. I am currently having a severe flare up in my abdomen and left thigh to the point I can barely move. I am on diuretics but they are barely touching the problem. I can’t get in to see my primary dr for two weeks. Any suggestions on how to draw the fluid out? Compressing the abdomen really isn’t an option I see working. In the past I’ve added protein shakes because my protein levels were low but that’s currently not the case. I feel like I’m a human beer barrel.
