Ah, thanks for that. Everyone has a different pain threshold, so surgically, it's hard to measure. But the gas pains.... ARGHHHHH! Those are vicious! I had an inpatient surgery and was hospitalized, back in the old days. But they still used gas during the procedure and even though my pain tolerance is pretty high, gas pains were brutal. To me, it felt like someone was sticking a knife in my gut whenever one came on.
Much later, I got some insight from reading others' experience. First, I learned the gas was looking for a way to escape my body. So I tried to make it easier by massaging and rubbing my arms, legs and torso. Believe it or not, this really helped.
A frequently shared remedy is using a hot pad. But I'd learned a better technique for shooing away local pain when I was injured in an assault years ago. It's called
RICE--rest, ice, compression, and elevation. Here's a link to detailed instructions:

So you may benefit from a heating pad or an ice pack, but RICE combines both remedies and it's proven effective.
On the other hand, you may have no pain at all. Fingers crossed! Don't let pain scare you away, though. Pain is temporary and manageable (drugs help). But making the change weight-loss surgery gives your body lasts a lifetime and opens doors to even more beautiful things.
