I'll tell you a few remedies and see if they work for you. I used 1 before. If there is a tooth cavity, put some monosodium glutamate. 2. Take a bite of fresh ginger. It tastes bad, but it works. You should first realize that these two pills are very effective if you can't exercise at high speed. If there is a cavity, crush it and put it in. This is no joke. I've experienced it myself.
