Hi all. I was hoping to get some opinions on what to do. Following treatment of my second occurrence of stage 3A ovarian cancer, I seem to have developed a problem called gastroparesis. Gastroparesis is a condition where your stomach doesn't digest food properly and it rots causing you to throw up. To confirm the diagnosis I needed to have an endoscopy. 

I had had one several years ago with just throat spray and it was horrific. My second endoscopy I had sedation and it went a lot better so this time I requested sedation which they did. The only gave me a very low dose however which didn't do anything. During the test they gave me botox injections to help my stomach with the digestion of food. They said that I need to have it again in 3-4 months. 

The problem I'm having is that my appointment today was horrific and I think the trauma is going to stay. During the procedure I started to vomit violently to the point that it filled my nose and I couldn't breathe. I tried to get the doctor to stop but he wouldn't. Luckily it was only 20 seconds and he took the camera out and I started to gasp. I've had two before and know what the feeling is like and how it is important to keep breathing but because of the vomit I couldn't and I was genuinely terrified. 

It left me hyperventilating and crying with a bp of 178/135 and I continued to vomit. I don't know how I can face it again in a few months time. I don't know if I just got a bad doctor or if it really will be like that everytime.from now on.

I would also like to add that I did fast for 10 hours but because of the condition the food hadn't emptied from my stomach.  

I don't know what to do. 

UPDATE 22/4/2021: Just an update that I have to wait to see if it works in 1 week and then it's a 3-4 month redo
