There are many reasons for headache when coughing, and the common causes are changes in blood supply to the head, peripheral inflammation, upper respiratory tract infection, intracranial hypertension and so on.
1. Changes in blood supply to the head: When coughing, the pressure in the chest and abdomen changes dramatically, leading to sharp changes in blood supply to the head, resulting in cerebral ischemia, cerebral vascular expansion and spasm, resulting in headache symptoms.
2. Peripheral inflammation: the periphery is infected by viruses causing inflammatory reaction, vascular expansion, pulling and stimulation of vascular sensory endings, causing lesions of the nerve plexus, triggering headaches.
3. Upper respiratory tract infection: acute inflammation of the nasal cavity, throat, nasal mucosal congestion, edema, common rhinovirus, respiratory syncytial virus and other pathogens, cough, nasal congestion, headache, sneezing, runny nose and other major symptoms, resulting in rhinogenic headache, common rhinitis, paranasal sinusitis.
4. Intracranial hypertension: severe headache, cough accompanied by vomiting, cervical rigidity, common in intracranial hypertension.
