oww that hurt, i hate it when that happens\nbrush your teeth after every meal and before going to bed and after getting up, keep your mouth as clean as possible, and if it doesn't go away in a few days or gets worse call your dentist back....you might see if the store has mouth sore gel, it helps to numb the area and cuts down on infection.

Your doctor can give you a prescription that can help it to go away and then began using it at the very first tingle if you feel one coming on again.  I have never heard the food connection to a cold sore.  Illness, stress, sun exposure are all things I have heard.  But, if you keep getting them, you definetly should be replacing toothbrush, toothpaste and mouthwash after every time or at least sanitizing them with boiling water.  Also are you using the same makeup, makeup aplicator or if you are male the same shaver, be sure and sanatize everything.  Change your pillow cases, anything that might have come in contact with your mouth, clean it or throw it out and start over.  Hope these tips help.  And sometimes if you are just run down and have been sick, your body has to rebuild and you might have several in a row.  I know I have.  Nothing over the counter will do the job like the stuff the doc. can prescribe, but it isn't cheap....:)  There is a prescription cream the doc can give you called Zovirax and it does help cold sores...

canker sores hurt bad, but they don't know what causes them.  some suspect a vitamin deficiency, stress, or some sort of trauma like biting. i will tell you that they are not herpes or bacteria, so you don't have to worry about that. you could go to your doctor or dentist, but they probably won't be able to do anything.  their is a product called KANKA that really makes them feel better. it numbs the area for a long time, and puts a protective layer over the sore so it doesn't get more inflamed. hope this helps, it works for me!

cold sores are an expression of the Herpes type 1 virus.  It is a mutation of the same virus that caused chickenpox in childhood.\nThe sores shed virus for as long as they are present, and for several days after they have dried up and gone away to visual inspection.  Touching the sores and then touching the genitals without washing your hands can transfer the virus to that region of the body as well, and guess what, then it becomes Herpes type 2, or genital herpes and you have it for life, can pass it along even if you don't have an active lesion.  A truly nasty little disease.\nThe cold sores that appear on the lips do so because of the proximity to mucous membranes in the mouth, they also are seen in and on the nose of those who are older and have had the problem for a longer time.  The virus lives in the nervous system, and the face is highly enervated, therefore the virus most often expresses itself there.\nTo avoid contracting the virus, do not kiss someone with an active lesion, or use their eating or drinking utensils.  Wash your hands after being around them, and do not touch your own face.\nNow, if you've had chickenpox as a child, you already have the virus in your nervous system, so even if you have never had a cold sore, the potential is there.

Try Blistex or some Bacitracin (antibiotic ointment).  Some people get sores or blisters and rash around the mouth from foods with lots of acid in them. AVOID LICKING YOUR LIPS!!!!!  Keep them clean and dry.  Too much oj or grapefruit juice irritates my mouth.

Well it means that you were kissing someone who had a cold sore....it is a form of Herpes and can be contracted via the oral/fecal route....in other words.....oral sex or kissing

Cold sore or a fungus of some sort.  If it doesn't go away in a few days go see a doctor.

Do you lick your lips while outside? Do you breath with your mouth open when you are in an area that is cold? Both of these could be causing your problem.\n\nCauses\nAngular cheilitis is most often caused by an infection—usually fungal, but it also can be viral or bacterial in origin. Other possible causes include a vitamin B deficiency, the over-closure of the mouth by someone without teeth, licking of the lips, thumb-sucking, and lip biting.\n\nLess severe cases occur when it is quite cold (such as in the winter time), and mostly happen to young children/teenagers. The child licks their lips in an attempt to provide a temporary moment of relief, worsening the condition.

It could be another cold sore. Go get some medication at the drug store the sooner you catch it the better.

Well Mister, I think you got yourself a staph infection from picking at your lip. This is not uncommon for a staph to relocate from your face area to a nicer climate, your lip. You'd better get to a doctor or an ER to get some antibiotics or?  Good luck let them know why it started, they may have a look at it, it could be an infected hair that's feeding it, it may have to be pulled out.

If you have a herpes virus that causes these ulcers to come up when you irritate your tongue, lips, or cheeks, there is an oral medication called Acyclovir that will help it heal.  However, we all bite our tongues at times.  Your dentist can give you a medication called Ora-5 that will help the area feel better while it heals.  The only way to stop these areas from coming back is to be more careful when you eat.  Slow down, a lot of people bite themselves when they are in a hurry when they eat.  I hope this helps.

Stress tends to make them appear.  So does fluctuations in temperature.  Try not to stress out. Apply lip balm regularly.  Abreeva works great.  Don't pick or play with the cold sore.  Scars are very easy to get.

A canker sore is like a wound, so it can get infected. There are glands in your neck (lymph nodes) that release antibodies to fight infection. In my experience, it gets sore similar to  the feeling of a stiff neck or when I slept the wrong way, when it is overworked. Once for a mysterious infection, I had to take antibiotics for two weeks and my neck felt sore all the time. Maybe your lymph node is just overworked from fighting off an infection in your canker sore. Afterall, the mouth is a pretty nasty place. Ask your doctor or dentist to prescribe you something.

Never got one on my nose, but I had one on my chin before. Cold sores come from a virus inside of you, every time your immune system is weak, it can break out. It usually breakes out on the lips, because the skin there is thinner and therefore easier to break through, but technically you can get a cold sore anywhere on your skin.

cold sores in the mouth are a form of herpes, herpes simplex two actually.  Stress and anxiety make this problem worse and so do certain foods.  There is no cure but there may be things you can avoid to make them come along less frequently.
