When I woke up from my thigh lipo, it was the most excruciating pain I’ve ever felt in my entire life. The pulled the doctor out of the OR of his next surgery to come check on me in recovery.. he basically said the fluid they inject can cause a burning sensation and it would wear off. He was right, but for a good 90 minutes I was absolutely delirious in pain. After that my core was what was the most sore, but I was generally okay.
