Hello thanks for choosing HCM for your health related queries I can understand your concern. Your husband of 82 years age has pulmonary fibrosis, asthma, emphysema and diaphragmatic paralysis. He is having severe pulsatile headache in episodes. As he is 82 years old and have chronic respiratory illness so his headache should be evaluated and investigated properly. If headache is very severe he should undergo MR imaging to rule out any vascular lesions though as symptoms are occurring in episodes so possibility is very unlikely. If his examination comes normal then for headache he can be given OTC analgesics like Paracetamol. Common medicines like Amitryptiline, Sodium Valproate can be used to relieve his headache. Medicines like beta blockers as Propranolol should be avoided because it may further aggravate the asthma. Visit a neuropsychiatrist for prescription. Thanks, hope this helps you.
