Took DD to Dr. because of a sore throat, she has strep. The Dr. also said that her thyroid is really enlarged and that she needs to have a thyroid profile and a scan. Does anyone know if thyroid problems are common in children? (shes 9) Will this affect her growth? I know these are questions for the dr. just could not think at the time so while I wait for results just thought I'd ask if anyone had any info. Thanks!
