Gastroparesis and Swallowing Fits

I contracted Covid in November 2021, I was healthy prior to that, some minor UTIs and kidney infections throughout the year, but other than that I was a “normal” 25 year old. My symptoms of Covid were all digestive problems, nausea, couldn’t eat, and bloating, just to name a few. I did a gastric emptying study as was diagnosed with gastroparesis. My colonoscopy and endoscopy did not show anything abnormal. I now have a G/J tube, and am on Reglan, Dicyclomine, Zofran, IV Hydration, Lansoprozol and have tried domperidone but my EKG showed concerns so I cannot take that medication. I also got a gastric stimulator implanted, which didn’t help me at all and settled under my rib so I chose to remove it instead of move it to a different location because it wasn’t giving me any relief or change in symptoms. I just got my stimulator removed last Monday. My question is, does anyone else get what I have named “swallowing fits”? It’s like there is a giant lump in your throat and hot lava coming up your throat and you do to swallow it back down but almost forget how to swallow? I know it sounds strange but it is incredibly anxiety provoking and is happening multiple times during the day. I had an esophagram that was also considered normal. I’m at my wits end with all of this swallowing and out of control nausea. I don’t know what else to do.
