NEXIUM DOESN'T FULLY RELIEVE PAIN

Yes Nexium doesn't necessary solve the cause. Your description of acid reflux which causes the tongue to be ripped appears clearly that your body has severe electrolyte imbalance and buffer deficiency. This is caused by the body's excess production of nitric oxide, which by the way is an effective way to get your tongue in such a s shape. The best way to deal with this problem is to take plenty of magnesium supplements (you can try magnesium chloride, or magnesium gluconate) and take some potassium (either try potassium chloride or potassium citrate). I personally much prefer magnesium citrate and potassium citrate in case the body's production of nitric oxide becomes excessive. Sports drinks do have some potassium, or electrolyte salts, read the labels, will have potassium citrate there, and this is one simple solution. Potassium bicarbonate, if you can find one will help as a support to magnesium.

However, I do have people with your conditions and found that magnesium, and potassium, in both citrate and bicarbonates to be most helpful, especially in dire emergencies as yours. One simple way to reduce that burning tongue is to rinse your mouth with some buffer solution. Try doing it with sodium bicarbonate and do it as often as you feel it is working. That helped a lot to, based on feedback. However, someone with a serious imbalance like you, might possibly use potassium bicarbonate as a mouth rinse to neutralized the excess nitric oxide (which is really nitric acid) in your tongue!

Just remember: mouthwash with potassium bicarbonate or sodium bicarbonate to neutralize the acid buildup in your mouth first. Then supplement with magnesium and potassium for a couple of days should help your recovery.
