I was wondering if my husband needs to set up an appointment with a Neurologist. He has had unusual headaches in the past week. Three times - sharp pain in the back of his head and today back and right side of his head (after sex). I m concerned because it has now happened within days of the other. About 4 years ago we were at a restaurant and he had a alcohol drink, that night he had such a bad headache that I took him to er (he was vomiting uncontrollably). They didn t find anything. Also, his sleep pattern is not good. Wakes up 5 times or more during the night. I don t know if any of this relates to anything, so I m asking for guidance. Thank you
