I had an endoscopy and colonoscopy on the same day. My experience was much the same as others. 5 seconds and then out like a light. It was the best sleep I've had in years!
Today I had a manometry test. I was very concerned because in addition to GERD, I have asthma and I am very claustrophobic. It wasn't as easy as the endoscopy, but it was not bad. No pain, just some discomfort. They put a gel numbing agent in your nostril and you sniff, this pretty much numbs your nostril and the soft palette. I was breathing through my mouth which kept me from involuntarily swallowing. Because I didn't swallow unless instructed the test took about 25 minutes start to finish. I drove home and I'm fine.
I'm scheduled for the Nissen fundoplication on the 20th and that has me very nervous, but my health as been so bad, that it can only improve. Any advice on healing from the fundoplication?
