Intracranial tension

Head injury, because morphine can cause increase in intracranial tension, cause marked respiratory depression and certain physiological signs e.g. miosis and vomiting can interfere with the assessment of clinical progress. 

Raised intracranial pressure could be a cause of early morning headache. Early morning headache could also be triggered by sinusitis, tension or muscle spasm.

The Mobility of the Intracranial and Intraspinal Membranes and the Function of the Reciprocal Tension Membrane... 

The reciprocal tension membrane (RTM) refers to the function ofthe mobility of intracranial and intraspinal membranes, the pia, arachnoid, and dura. Understanding the development and the anatomy of the membranes helps illustrate their function (see Section X, Chapter 102). The intracranial membranes are intimately related to the fascia throughout the rest of the body.

The causes of headache are many and varied. Some are life-threatening, such as intracranial aneurysms or bleeding, meningitis, or have the potential to be such as hypertension. Thus, the physician must keep these in mind when treating a patient with severe headaches. However, the majority of headaches are caused by muscle tension or migraine. A 28-year study at the Headache Unit of Montefiore Hospital found that 90% of headache patients had migraine, tension headaches, or a combination of the two.
