It could be said that mathematics is the language of physics. That is another way of better understanding what is physics.

In brief: Cough headache. There are a couple of possibilities. Coughing can raise the pressure inside your head, which can cause pain sometimes. There is also a poorly-understood entity called the primary cough headache,  that is associated with coughing, straining, laughing, crying, etc.
The causes of this kind of cough are many. Infections, bacterial or viral, acute or chronic, could be the cause. Other possible causes include airway problems, foreign bodies caught in the throat, tumors, heart disease and the use of pharmaceuticals (especially ACE inhibitors).or now, if you suffer from a cough that lasts longer than eight weeks, ask your doctor or specialist to do two things: 1) Help diagnose any condition that may be causing it; 2) And help make your irritated throat less sensitive to the harsh reality of a cough.
