Male, Had Lipo of Abdomen, Flanks and Pubic Area. My Scrotum is Enlarged to Size Of Baseball?

I had abdominal, flank and pubic liposuction yesterday. I am wearing the compression garment and pain is okay. Drainage of fluid is proceeding as normal. My scrotum is about the size of a baseball! Afterwards, I could not urinate without pushing VERY hard. I went to the ER later that evening (just last night) and had a catheter put in. Now I am flowing freely. I fill up the bag every few hours. Is this normal? Should I get it removed soon? I'm afraid I won't pee on my own if removed.
