Hi,
How is your daughter? Cough headaches can be triggered by coughing and also sneezing, blowing the nose, laughing, or crying.  Primary cough headaches are usually harmless. But secondary cough headaches are more serious because they are caused by structural problems within the brain. Primary cough headaches tend to occur in limited episodes and  improve on their own. If it persists, further evaluation  is needed to rule out secondary cough headaches. Take care and do keep us posted.
