It could be said that mathematics is the language of physics. That is another way of better understanding what is physics. Numerical values, units of measurement, and similar concepts are all mathematical in nature, and are used to describe physical quantities in the most accurate and precise manner.
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.
Secondary cough headaches may be caused by: 1  A defect in the shape of the skull. 2  A defect in the cerebellum, the part of the brain that controls balance. This can occur when a portion of the brain is forced through the opening at the base of the skull (foramen magnum), where only the spinal cord is supposed to be.
