No follow-up after my endo/colonoscopy. I thought he was testing for celiac. I had to request an appointment and could only get telehealth. I waited for the call, and it never came. Then I discovered that a TEXT was sent and I was supposed to click the link. I was unaware I should be looking for a text, so didn't even check that. I don't understand why he couldn't just phone me, for Pete's sake!

my problem. He was the 3rd Dr to
remind me I was 90
