hi madam
thank u for contacting us here
your boys have a similar problem ,at the same time ,that too without any
fever...it's a bit strange,but I first would ask u few questions to rule factitious illness
1. as you have checked them ,n their temperature is normal,next would be just look all over the body fr any rashes..it could still be a viral eruption
2. ask your school about similar issues in children...it could be viral thing going around.
3. even ask them about any specific food intake outside
4. ask them separately abt any school issues like bullying if you strongly feel their symptoms to be fictitious
5. last but the most important,,,see ur family
pediatrician at the earliest, which would actually solve this issues just in case they need blood checks
6. give dm hot supper ,soup with boiled veggies at short regular intervals....
regards
Dr sowmya
