Hello, my 16 yr old son , 3 days ago had to be rushed to the E R for a severe headache, on the right side of his face, head, to the back of the head. Ct scan was normal, blood ct was normal. Migraines run in the family. Tonight his R eye is swollen. He is sensitive to light, sound. Pain is still there with migraine Meds,, & Norco. I m sure this is not a migraine. Prior to this severe pain he has had a dull headache for a few days. Please help thank you so much.
