OHSS - tips for easing pain and discomfort?

M
After terrible bloating and pain the past few days, I found out this morning my ovaries have hyper stimulated. There's a good chance I'm preg (my hpt are positive and urine test at doctor's was positive but then changed to negative - they did bloodwork to confirm) so I can't take much and they'd like to avoid draining me if possible. Any tips on how to ease the pain and/or reduce the swelling?
