The Left Side Of My Mouth Is Split Open And It Won't Heal, What Do I Do ?

I have the same thing.  It's due to your spit.  It's got a lot of acid in it.. Sometime because of to much sugar in your diet.  The acid bothers your lips and causes irritation on the corners of your mouth. Then fungus grows in the moist area.  Fungus and acid irritation can cause small cuts that just get bigger with time.  It's the same type of fungus you get on your feet..  Foot Fungus cream may help a little ( I've used it before on my mouth lol) ,.... But a doctor will be able to give you anti-fungus cream for your mouth.

Sounds like angular chelitis. I get these frequently, and feel your pain. I haven't found any over the counter applications that work, but my doctor prescribed an anti-fungal cream/ointment that alleviates the pain and heals the wound.

I have the same problem currently and on both corners of my mouth.I'm glad I'm not the only one walking around feeling like the joker.But I can tell you this if you put on abreva every night before you go to bed and every morning when you wake up it helps heal the wounds.it also helps to put on vasiline cream as much as you can to keep it moist.Also if you have a bump on your neck or under your ears like I have and had don't sweat.its a swollen gland.drinking lots of liquids and taking benedryl or tylenol will help ease the pain.It should be gone within a week or two.if not then see a doctor the bumps could be mumps.All of these usually happen after you've fought an infection its how your body heals.

I've had this off and on for years, and just forget to mention it to the doctor's, myself... Now, my daughter is having the same problem... I've been told it's probably either viral, like a canker sore and crops up when you have another viral infection such as cold or flu, or due to acidic digestive tract, or even yeast-related. Sometimes I can get away with only applying Carmex or some such, if I catch it early. Others, my diet has to be played with and Carmex seems only to help, not take care of the problem. The corners of my mouth are now slightly discolored all the time from the scarring, so definately take it to the doctor, find out what it is for sure or you could have it reccur enough to scar, as well! I'm taking my little girl in next week to find out myself... Good luck! =)

Is it in the inside or the outside?

This happens to me in the wintertime, or if I've been out in the sun too long.  I use Neutrogena's lip balm -- constantly.  Carry it around with you, and apply it every chance you get, so that the split is kept moisturized.  You should see it start to heal within a few days.  The key is not letting it dry out -- the moisturizer keeps it soft so that the skin can be flexible when you eat or talk, and won't split so much.
 
I hope that helps you out, and I truly hope it helps solve the problem for you.

Hi

sounds like same here.  Its a fungus so try some clotrimazole cream for the fungus (9.00) and some cortizone cream as well... If you mix these two in one tube it requires a prescrip.  

Best of luck.. Yes its similar to the foot and jock itch type fungus.... Nothing that is real unusual

Lol when I read the question I imagined you had split your cheek with a knife or something. Anyways if it is chapped lips and stuff then get a good healing Chapstick (not a cheap flavored one.) you can use the cheaper chap sticks after you're healed. And you will have to use chap stick if you don't want this to happen again. Personal expierience

The best advice I can give is, you should go to see a doctor.

I had an Esthetician tell me change to change my toothpaste and it healed mine.
