Be careful...the alum reacted negatively in my mouth and cause a more severe outbreak.

Hey I just started using Alum tonight, and it hurt really bad, I mean horribly. And it's still burning. Will it be better in the morning? Cause I'm freaking out cause my canker sores hurt so much worse when I put the alum on it.

Okay, so I get canker sores every so often, esp. when I don't get enough sleep. This particular monster sore on my lower lip started when I severely bit into my lower lip TWICE on the same spot a week ago. No signs of healing. And they usually do after a week. Not this one. So someone suggested Alum. A quick search online brings me here where there is a lot of positive feedback. So I put the Alum on and like the above post, the pain is pretty intense. Tears are leaking involuntarily out of my eyes. 5 minutes go by and I rinse it off. It's now about 30 min after and the sore feels like it's twice the previous size. Totally swollen. And it's throbbing like no tomorrow. If it gets better, I'll be shocked, but I will report if it does in the morning.

Ok! When I'm stressed I bite the inside of my mouth. Yuck!! I know! This can lead to the MOTHER of all canker sores. My dear friend just told me to dab alum into the canker sore, hold the affected area out so it can settle into canker sore and not be washed away by saliva. Let me explain. What I have going is a flipping cluster of sores( 12 in total. SERIOUSLY!!) A few are about 1/4 x 3/8. No I'm not joking. So I apply the alum out of desperation. I'm in constant pain, my lips aren't working. Drool is running down my chin(SEXY right?) AND i CAN'T eat. Ok the alum feels like flipping battery ACID. I want to rip half my face off. Who cares that it tastes viley bitter-it REALLY hurts. It does not sting. Serious PAIN. After about 20 minutes half my lower jaw is numb. Thank God!!! It feels a little swollen. I look in the mirror and honest to God it looks like I've just had half of my mouth pumped up with whatever that crap is that make you look like a freak of nature! I live in newport beach-the land of the plastic fantastic. Please tell me that this will subside and I won't look like a middle aged woman having a midlife crisis and a budget to only cover half the job! Frickin' Y-I-K-E-S !!!!!!!!
