Unexplained Weight Loss/Inability to Eat

My medical history: Appendicitis, Gallbladder Removal, Pancreatic Duct Issue & Hiatal Hernia in the past 15yrs. Upper gastric left pain after eating, exercise or lifting something heavy. Also causes dizziness, feeling lightheaded, 35lb weight loss, deep belching, bloating, foul gas and chest pain. Tests: EDG, Colonoscopy, MRI W/O Abdomen, pelvis, brain, back, chest, CT CTA Heart, swallowing study, GP study, blood work, urine, fecal matter, ultrasound, MRA for vasculitis and 16 doctors, 4 GI = nothing. I follow no Gluten, dairy or red meat, alcohol because it makes everything 100x's worse. Small meals 3 - 4hrs a part, no exercise and I own a farm, that I can no longer work. I take Zofran when the nausea hits. It feels like things just chug along very slowly...doctors just say, it's not cancer, be grateful. I was an athlete, small business owner, avid horsewoman, never watched TV and I don't know why. It seems to be all on the left side, tinnitus, HB in my ear, numbness & tingling and it feels like something is pressing on something. Anyway, new doc appointments are 4-5 months out. Any clue to go next ?
