You need to meet another good specialist. It is unfortunate that there are lots of barely trained "specialists" with the CPS diplomas in your state, who are not valid to practice elsewhere in India! Use the Practo app to select a good ENT Specialist based on good patient feedbacks. Any decent ENT Specialist would have scanned the Nose & Paranasal Sinuses to rule out sinusitis as a cause of dysphagia and not throat! Reflux Esophagitis is another condition that should be ruled out. Discuss both these probable diagnoses with your next ENT Specialist.
