I've had 15 adjustments in 2 years, and none of them hurt. A few times I went away with a bruise, but so what?
If a fill hurts you, ask for a numbing shot (or spray) the next time. In my experience, the numbing shot hurts worse than the adjustment needle, but again, so what?
And doesn't the pain of a fill compensate for the pain of all your medical problems?
Would you enjoy giving yourself insulin shots 4+ times a day?
What could be worse? How about chemotherapy? How about a broken leg? Or a brain tumor that makes your body disobey the most basic commands?
A band adjustment takes maybe 10 minutes. Your life takes you maybe 87,000 minutes? That works out to .000149 minutes per adjustment. A small price to pay.
