Hi, My son just turned 4. He had a severe headache for 3 full days. The headache was bad enough to stop him from eating or moving. If he stood up, he screamed in pain. The headache was localized to the top of his head. After day 2 of the headache, he developed a small rash on his face around the left side of his mouth. Within the past year, my son has had a few black out episodes and a couple of seizure like episodes. An EEG test showed normal, however, the EKG showed High voltage and confirmed a heart murmer that can be heard. I am very concerned from the headache. Could this be related to the heart or something further?
