Allergy Headach

My 5 Year old son hasbeen having headachs the past couple days. I give him some pain med. and I give him some stuff for allergies, it seems to go away until the meds. were off but his headach is always on the right side of his head near the temple and I am getting a little worried like is it def. his allergies or could it be something else? If anyone has any input in this this would be great.

Hi,
How is your son? Was there a previous trauma to his head or neck? Headaches may be due to eye, ear or sinus problems, allergies, trauma, or primary headaches such as migraine or tension headaches. If it persists, have this evaluated further by your doctor for proper management. Direct clinical examination and complete neurological examination are important. Take care and best regards.
