seroma advice please desperate

I had a mastectomy on Sept. 18 and about two weeks ago my drains were removed. When they were removed, they were at about 20 cc. Since then, I have been having fluid build-up. My doctor's PA told me to wear a compression garment (girdle) which I have been doing, but it actually seems to have made the problem worse. I feel the seroma on the mastectomy side is worse, and now I feel fluid on the OTHER side where I had a previous mastectomy on the other breast in January! I had two mastectomies, one in January for cancer and the other in Sept. as a preventive because I am BRCA 1. I am supposed to go to the doctor on Tuesday and am going to demand to see the doctor himself, not his PA. Last time (for the first mastectomy) I also had fluid build-up, and they ended up having to put the drain back in, but it was a different circumstance: that time the drain popped out by accident on the second day after surgery which caused the problem. This time I was super careful not to lose my drains. It especially worries me that I feel the fluid build-up on the side of the first mastectomy which had previously gone away. I'm wondering if somehow the compression garment could be making it worse? Any advice would be appreciated. I am so depressed about this. Ohilly
