Can I wear the compression garment by Marena during the day and spanx to sleep?

I had smart lipo on 3/17, almost 2 weeks ago. I didn't have a huge amount removed. So far I think I'm healing nicely, still sore and swell more as the day goes on. My surgeon said to wear the compression or spanx 24/7 until I see him again (4 wks p/o).Does it make a difference if I wear a compression garment (Marena) and Spanx (full body) and pretty snug at night? I tend to swell a lot by the end of the day so the garment gets uncomfortable. Will wearing 2 different ones matter?
