Hello & welcome to Just Answer!

If you have any questions after reading my answer, be sure to let me know.

I can understand you anxiety, since a sick child is tough to deal with, and one with a headache always 'suggest' possible serious disease

There a few positive things though

1. he has a mild runny nose/ congestion, this can be accompanied by a headache

2. A pediatric evaluation did not find anything unusual

3. he has pointed to both sides, making a local cause less likely

I would agree with the pediatrician's advise of waiting for a couple of weeks

since further testing / neurologist appointment can be delayed for this much time in the absence of any medically worrying symptoms ....

Ok

An ear infection / inflammation in the local area is more likely

but since the pediatrician did not find anything unusual, a few more days should be appropriate in the absence of high fever, worsening headaches, vomiting, excessive irritability etc.

From your description it does not raise a 'red flag' at present

:)

You are welcome

The running / shaking can worsen almost any headache, and do not point to anything serious by themselves

The common cause of headache in small children include viral infections, cold, ear infections, tooth infections etc. and these are rarely serious
