Treatment: Using over-the counter pain medicines, prescription drugs, if having chronic or bad pain, avoiding things that trigger headache.
Statistics: Different studies have reported an overall prevalence rate for tension type headache ranging from 5.5 to 26% in children between 6 and 12 years old. In a recent epidemiological study in Germany, the 6-month prevalence of headaches was 53.2% among children from 7 to 14 years
