Persistent Nausea Help

In 2017 I went to a restaurant and ended up vomiting. I then had about 3-4 months of on and off nausea with no vomiting. I had an endoscopy which only revealed potential EoE, but was primarily diagnosed with GERD. An ENT also thought it was LPR at the time. I’ve been able to manage over the years and haven’t had much nausea but recently I had a stomach bug which caused me to vomit and I am again feeling the nausea sensation. I’m wondering if the acid damage from vomiting caused some sort of damage to some nerve or if there is some other GI issue going on. Anyone experience something similar?
