Common symptoms of acid reflux include chronic cough
(cough that lasts for more than 1 month), epigastric burning, fullness, heartburn and "waterbrash" (sour taste in the mouth after waking up). You are taking high dose proton pump inhibitor (lansoprazole
), thus your gastric acid
levels should be supressed.
Things to look for would be any dark or bloody stools, or other evident sources of bleeding, since you are taking dual antiplatelet therapy, and this could lead to gradual, chronic blood losses. It would be ideal to have a hemoglobin checked to make sure no blood loss anemia
(common cause of fatigue) has happenned.
If the symptoms persist for more than 4 weeks, it is less likely to be a viral or bacterial infection; however, some viruses like Epstein Barr (cause of infectious mononucleosis
) can cause fatigue that lasts for months, and one of the presentations is with a "bad case of sore throat".
Hope this helps.
