<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have had an endoscopy done last week. Nothing was found. I then had an ultrasound of my gall bladder and all was clear. I still have short bouts of nausea. I do have an inner ear issue with tinnitus and some minor high frequency hearing loss . Any ideas on the nausea? I currently take omeprazole daily and Gaviscon liquid on a needed basis.  <response>: Dear friend, welcome to ChatDoctor.it clearly is an inner ear issue. Tinnitus, hearing loss, nausea are symptoms of ? Labyrinthitis.or other lesions do you have imbalance while walking? And giddiness rotation feeling?I think you should be visiting a good ENT specialist who is good in middle ear and labyrinth problems. You can try labyrinthine sedatives antiemetic still then. Take care and keep me posted on your progress. Good luck !
