Do I really need to wear a garment and yoga mat after Smartlipo?

According to the Dr. I must wear a piece of yoga mat that goes all arround my stomach before putting the garment and also a thin shirt underneath the mat so it doesnt burn my skin. The reason why i have to do all this is because he doesnt want the garment to make any dentations on my skin which can be permanent. Now to me all this is way too much and super uncomfortable specially when i have to do it 24/7 for 4 wks. What can i do? Thanks!
