I have been having really bad headaches… Tension in the cerebral area, sensitivity to light and sound. My doctor looked at my tonsils, and saw that they were very large, which is normal for me,… she assumed that my headaches could be caused from lack of oxygen to the brain when sleeping or sleep apnea caused from my large tonsils… Can teens get sleep apnea? And is it extremely harmful for a teen to get? I am only 17… thank you!
