DD age 3 has a swollen thyroid..this was noticed by the health visitor 6 months ago...took her to doctor who took blood to test her thyroid function..came back fine..said he would recheck her thyroid function in 12 months(which would be this coming september)..was very worried so took her to another doctor for a second opinion and he agreed with first doctor and said he didnt think it was anything sinister or she would be ill and that she didnt need to be scanned...took her to doctor yesterday for something else and asked him to check if it was still swollen..he said it was and said he would send her for an ultrasound of the thyroid,but it might take a while for an appointment..asked him why it would be swollen all this time and he said it could be viral....obviously I am scared and imaging all things..refuse to google as that would drive me up the wall with worry..so if anyone knows anything about this or been through it with a child your advice would be so welcome..
