How long does severe sharp pain last after CoolSculpting?

I received my first Cool Sculpting treatment exactly one week ago today. Four days after my treatment I developed severe pain. Feels like stinging sharp pain, sometimes so bad it causes me to jump. It appears to be worse at night. It also resonates to different parts of my abdomen. I am extremely swollen, I am also numb and itchy. I saw my doctor yesterday, he suggested tylenol 3. Unfortunately that does not touch the pain. I have been awake now for 4 nights in severe pain. What can I do? Thank you
