Private gastroenterologist

Happy Friday to whomever reads this post,

I need some help deciding on where to go to get help with my stomach issues. Now I've done an endoscopy and a colonoscopy before. Both were done publicly and it was honestly a shit show (excuse the pun) I won't go into detail with how how awful my experience was, but they really proved to be little to no help.

Although I got a diagnosis, I feel like more was needed. I'm not sure if it's a thing they'd do, but I was hoping to be able to figure out if I've a leaky gut, or if I'm digesting my food correctly.

So has anyone been treated by a private gastroenterologist that they would reccomend? How roughly how expensive was it?
