My 17 year old son had his wisdom teeth removed 5 days ago. While the first few days showed no complications, the past two nights he has woken up with a severe, painful headache in the middle of the night. I took him back to the Oral surgeon yesterday and he said that it was nothing to be worried about. The pain for my son is absoulutely excruciating. Could this be damage to his sinus? How long do we put up with the pain?
