Aww I'm sorry about your Hubby, hopes he feels better soon! You must be exhausted as well!
I work in urgent care and we get a lot of patients who have migraines and they look like they are in SOOO much pain, and we usually give them Ketorolac (Toradol) for it and it seems to help, I haven't heard of Midrin, so im not sure about that..
But I've had migraines myself in the past, and it is just the worst pain ever, feels like your head is just AHHHH, it's a painful thing it just comes and sometimes it just stays there (well for me at least).. this was long time ago.. I get really bad headaches, but they aren't migraines, mine last all day long and sometimes when i wake up.. i think mine is pregnancy related but who knows
But I hope your hubby feels better soon!! and you should get some rest as well!
