What if Coolsculpting sessions too painful & I can't stand the pain after paying for all the treatments?

I am about to commit to a series of cool sculpting sessions at a price over $5000. My first experience with another provider proved painful as a toe curling case of kidney stones. Each area was different so I expected a mitigation of pain but I was wrong and somehow got through. The new doctor's assistant stated they don't provide any prescription strength med. This new round involves 3 hour sessions. What if I can't stand the pain after paying for all the treatments ? Can I get any refund?
