Ok, so my family and I just took a trip from Augusta, Ga to Missouri to see my grandmother.... The last day we were there, ( the day we left) my 5 year old son started complaining that his teeth were hurting.... I called my mom who was a dental assistiant for 25 year's, and asked her what that was all about and she said that sometime's when your getting a sinus infection your teeth can hurt....But a few hours later, he started complaining that his lips were hurting.... I looked at his lips and they were white on the inside, and chapped on the outside... I figured it was because he was picking his lip which he does a lot.... As we continued our journey home, he wouldn't eat....I just thought that maybe he wasn't feeling good... So, eventually I looked in his mouth and he had this yellowish white coating on his tongue.. At first I thought this was Thrush but it wasn't completely coating his mouth.. It was just on his tongue.... And his breath was so foul..... Eventually, he wouldn't eat... Being 3 day's now not eating, when we finally got home I took him to the ER and they told me that he had oral herpes.... They gave me "magic mouthwash" for his mouth, so he could eat, antibiotics, and a pain medication..... He's doing a lot better now, but question is this.... Back in April of last year my 12 year old niece molested my son..... I was wanting to know if that could possibly be the cause ? Or if it's something he could have caught at Pre-K...... I know now that my son will have this horrible thing for the rest of his life... And it's so heart breaking...... Has anyone else had this happen ? I have heard that some dr's use Valtrex, but what it's not safe for him... Anything else?
