Yes, you do have the classic symptoms of GERD. I have experienced all of this plus the ear pain. If the Prilosec is working somewhat, then you may have GERD. These meds don't always work 24/7 like they say. The most I've ever gotten out of them is 16 hours before I started feeling pain again. Sometimes you won't feel the acid coming up, but if you have a red tongue or a burning tongue, then it's probably acid. The first sypmtom of heartburn is pain after eating something like a burger, so I would say to get to a doctor to have a few tests to see what's going on. This will give you peace of mind...not knowing is worse.
To get some relief for now if your throat is raw, get some aloe vera gel at the health store and drink a couple of swallows about 3 to 4 times a day. Drink Ginger tea for relief also. Try combining it with camomile tea..it is more palatable. There is also Orange Peel Extract at the health store which helps me alot. At bedtime, try to elevate your head and torso with pillows to keep the acid down and sleep only on your left side, this keeps your stomach lower than your esophagus. I'm afraid burgers are out for a while, try eating a more bland or alkaline diet, alot of veges and fruits, no coffee, tea, cola, alcohol for awhile until you improve. Also, chewing gum relieves acid because your saliva is alkaline. There is also DGL licorice which soothes the esophagus and acts like a natural antacid. All these remedies have worked for me at different times.
Hope this has helped you. Good luck. Sillylilly
Try some of these and see if they help
