I have been experiencing severe sore throats, a bitter taste in my mouth, chest pain, and stomach pain, and occasionaly dificulty swallowing for about 5 months now. My doctor put me on prilosec otc which seemed to have helped for about a month. Then he had me try protonix . I stopped that after 4 days bacause it made me sick to my stomach. The he had me on zantac (which also didn't work), now I' m on nexium twice a day. I've only been on that for a couple of days so I guess we'll see what happens. I went for an upper endoscopy yesterday and found that there was a lot of bile in my stomach. H e took biopsies of my stomach and esophagus so I'll find out the results in a week. The constant sore throat is really bothersome. Does anybody have any suggestions? If it turns out to be bile reflux I hpoe there is something that can help.
