Canker sore....like a pebble in my shoe!

I have had a canker sore several times this month in the same spot. On my lower lip right where my lip touches my teeth and gums. It is absolutely driving me insane, and quite painful at the same time.
Well I am fed up! I have been researching some remedies and found a few that I will trying this evening.
But for all you canker sore victims you may want to try these few, I know I will be this evening:

• salt Salt water is another remedy you can use. Mix 2 tablespoons of salt in a 6 ounce glass of warm water and use as a mouth rinse 3-4 times a day. Both alum and salt help draw fluid from the canker and help it to heal.
• Antacid formulas, such as Mylanta and Milk of Magnesia, used as a mouth rinse for a few minutes have been reported to relieve the pain and speed healing.
• Baking soda is another time-honored remedy. It can either be used as a powder directly on the sore or made into a paste and applied. Use several times daily. It may sting a bit, but it works by reducing the amount of bacteria in the mouth.

I know this is a crazy post, but I am sure I am not the only one who suffers these painful nuisances so hopefully these remedies will work !
