<s>[INST] I had surgery about 8 or9 yrs ago for a hiedal hernia in my stomach. My esphagus was damaged and for the last three weeks I ve had a dry spot in my throat. I caugh and I won t to throw up but nothing comes up. For awhile I felt like I had a ball in the middle of my throat it longer feels like I have the ball. The caugh is still their but irritating. I have asthma and when I needed it irritates and makes it worse. Since my surgery my voice changes sometimes I loose my voice. [/INST] It might be Castro esophageal reflux disease. Due to weakness of Castro esophageal picture reflux of acid from stomach will induce choking sensation in chest and throat. It will also provocative asthma. Avoid lying down position for at least 90 minutes after meal. Omeprezole or pantoprazole or rabeprezole for five weeks will help. Local anesthetic plus antacid preparation for four time a day will also help. </s>
