Hi,
There are a few issues with your son.
#1
It does sound like a
concussion but it does not sound like he is properly being treated. Concussions are not just "go home and rest" and require specialists to manage. Brain rest is the principal treatment. Most
Sports medicine doctors can manage concussions and some places have specialized "Concussion Clinics". Unfortunately, children actually do worse than adults if not treated properly and take longer to heal (one of the rare issues where children actually recover less easily than adults).
Some concussions will make a child miss a semester. By not treating a concussion correctly, concussion symptoms can linger and worsen. Imaging is generally not needed for concussions. Major symptoms of concussions include:
headaches, light sensitivity, mood changes, concentration problems,
fatigue, irritability, and balance problems.
#2
Mucosal thickening is most likely a little bit of allergies. If he has no symptoms, he does not need to see anyone if he has no sinus congestion or
nasal congestion.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Timothy Wong, General & Family Physician
