Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Does your daughter have a fever? Has she ever had blisters like these before? Has she been exposed to anyone with fever blisters? Since these might be contagious, avoid kissing and sharing drinks and cutlery. Please see that she drinks adequate amounts of fluids and takes acetaminophen or ibuprofen for pain. Blisters persist for about a week. I wonder if it hurts her to have a bowel movement because she is impacted. Children who don t have a BM regularly can have accumulation of large amounts of fecal matter in the rectum and colon and this part of the intestines can become distended. This may be giving her the abdominal pain. You may wish to take a look at the toilet bowl before she flushes to see how large the stool is. Children who become impacted can pass stool so large it can block the toilet. See if the bed wetting stops. Fecal impaction(and we don t know she has it) can be associated with wetting bed. I hope this helps you. Please return if we can assist you in the future. Arnold Zedd, MD, FAAP
