Help me with the problem! The issue.

I have been facing this problem since a year, a year ago suddenly I started feeling dizzy and was hospitalised for food poisoning, but after discharge I still faced severe vomiting and dizziness, I met a gastroenterologist, after taking his medication I felt good but I had problem such as dizziness and uneasiness in my abdomen, then I started having panic attacks, like I felt breathless and pressure on my abdomen, I am on medication for the panic attacks, but i still face the issues of dizziness, uneasiness in abdomen, muscle spasm, uneasiness in the entire body. My MRI of brain, spine, 2d echo colour Doppler, endoscopy is normal. Could this be related to my liver, because I used to take weight gainer a year ago and suddenly stopped taking it. Please help with the issue.
