Hi... Welcome to healthcare magic.. According to your complain you have problem of difficulty in swallowing that may be because of esophagitis ... Diverticula also cause difficulty in swallowing.. esophageal spasm also cause this problem... gastroesophageal reflux disease cause oesophagus ulcer and narrowing of esophagus.. You are taking alcohol drinking that can cause damage.. Detail history give exact idea... Barium swallow can use for further diagnosis.. Laryngoscopy examination helpful.. Any lesion present than biopsy can use... Manometry to check pressure in oesophagus during swelling... Consult a physician for further diagnosis.. I hope my guidance helpful to you... Take care. Thank you.
