My son (almost 11 months) has thrush...at the same time we noticed the white spots in his mouth, he developed a blister on his lip and right above his lip? Could thrush cause this? Or sun exposure? We don't have him outside too much - it is so hot here - and we use sunscreen, but I never put sunscreen on his lips (and might have missed the area right above his lip. Or could this be a fever blister????

Hi B. W., I've had thrush so many times I can't count any more.Absolutely sounds like and appears to be thrush. Antibiotic use and mold and/or mildew can cause thrush.In the home(mold/mildew) somewhere or possibly a contaminated object the child is perhaps being exposed to.Not a doctor,of course,just a couple of things that can happen. I ,as an adult,of course, have been given the nyastatin treatment .I can't recommend a treatment,only for you to get the child to a doctor.God Bless. S. L.

Oral thrush usually only involves the inside of the mouth, from my understanding. If you have herpes simplex A, or he has been exposed to it, then the blisters outside of his mouth could be a cold sore. Often times, if our immune system is compromised-especially around the mouth, then you are more likely to develope a cold sore. Is the sore crusted looking and oozing? Or is it just a clear fluid filled blister? The first is classic symptoms of a cold sore and can be treated with a topical application of L-Lysine. If its a smooth fluid filled blister it could be from the sun or even the thrush, but as I said I do believe that usually presents inside the mouth. If it doesnt seem to be better by Tuesday you should take him to the doctor.

Two of my babies had thrush. We tried everything to get rid of it. What worked the best was feeding them plain yogurt three times a day. Schedule an appointment with your pediatrician to have the thrush looked at again.

If he's using a paci (or sucking on something else alot), could be a "suck blister". Usually occur near center of upper lip. Good luck with the thrush.
