Hello, I read your message and understood your medical issue. I think this man must be sent to the hospital to do some examinations and to consult with a doctor. These symptoms and their rapid onset may be related to many diseases some of which may be dangerous. A migraine with aura is a possible diagnosis. This is a type of a headache associated with strange sensations and sometimes with nausea and chills. The sense of disorientation associated with nausea and chills can be related to vertigo which can be caused by an ear infection, ear toxicity etc. or if it is due to a central cause it can be more serious. An ear examination with an otoscope by a doctor is the first thing to be done followed by the general examinations including the neurological ones. Ear infection is successfully treated with drugs (antibiotics if the cause is bacterial). If the cause is something by a central origin a head CT scan must be done. If this is his first attack of migraine he must be careful to distinguish the triggers of his migraine headache and avoid them. OTC pain relievers are usually enough to control this type of headache. Next, if the worker did not use to have his meals regularly, drops in blood sugar levels could be a possible cause. Measuring his blood pressure and blood sugar levels will give more clue regarding his health problems. At the end, I am still thinking that this man needs further evaluation by a physician in order to take proper measures in time and prevent future episodes. Hope this is helpful for you. Dr.Albana
