steroids like prednisone 20mg often will upset the stomach and cause the stomach to produce more stomach acid which can cause acid reflux stomach acid to come up the esophagus and cause acidic taste in your mouth.
nexium is a prescription stomach acid blocker.
you can use over the counter stomach acid blockers
prilosec is omeprazole, a proton pump stomach acid blocker just like nexium, but in 20mg dose over the counter.
you can use prilosec and zantac and maalox and mylanta over the counter to block stomach acid and decrease acid reflux
you should also avoid alcohol, spicy foods, tomato sauces, oily or fried foods, large meals which can cause acid reflux.
you do need to eventually apply for health insurance so you can pay for treatment.
at your age of 71, you should be elegible for medicare insurance which covers 80% of doctor's visits.
make sure you take the steroids with food in your stomach, never on an empty stomach and taper them down when you stop them
