This occurs sometimes at a random moment and it seems to be most heavily from the nose down to the throat. The acidic taste is from only the right side of the throat but not the left? Please help! I want to solve this now with medication without visiting the doctors

It sounds like post nasal drip to me (which to me tastes more sour than acid).
Try different decongestants and mentholated cough drops.
Acidic might be acid reflux, but that would be from your esophagus to your throat.

I just had it 15 min ago... and it burns every time I swallow. But thanks so much for the great tips I will try those!:)
