i have had these things my entire life (34 years). they are painful, ugly and not easy to get rid of. Here are some of the things that i do when i get one....... any of these have helped me. I just prefer some over others. I get the VIT E gel caps and poke a straight pin through it and put it straight on my sore. Then i swallow 3 of them in the morning. and 3 at night. you might not want to do that many for your son. I have also used ice to freeze it. Aveeno makes a cold sore medicine that works very well. only need alittle bit. Remind him to wash his hands if he just touched his mouth.(yeah right he is 3) and dont use the same wash cloths on his mouth. they are very contagious. also wash the pillow cases.
Watch what kind of foods he eats. foods with alot of acidic content to them will break him out fast. Citrus, oranges, grapefruit, pineapple, tomatos, and sounds crazy but POPCORN. Something about it makes you have a break out. Sun,will make you have a break out. Summer is worse but remember that uv rays are present even in the other months. Dont let his lips get dry and cracked you can almost always bet on a cold sore.
As you may already know Stress is a big factor with cold sores. But what stress can a 3 year old have. well they have their own kind of stress that is big to them small to us. Try and notice if he seems to be a bit stressed when he has a break out. new school, kid not being nice to him, etc.
This is a virus Herpes. and it is something that we cant get rid of just have to live with it.
Good luck and if you have anymore ??? feel free to email me. Good luck
