I have been having problems with MOH headaches. I have also been diaganosed as having refractory headaches which are those that do not respond to treatment...yay for me!! I was told by my new neurologist that the next migraine I get I should come to his office and get about a 45 minute DHE IV treatment. I have read other posts on this site and there is a lot of talk about this being a 3-4 day treatment. Are there different types of this? My dr. told me that I need to limit the use of imitrex to try to get rid of the MOH headaches, but this is so hard, due to almost daily headaches. Last week I ended up going to the clinic and getting a shot of toradol and an anti nausea shot. This broke the migraine cycle for 4 days, but today I got a migraine. Of course it's a Saturday and my doctor is the only one in my area who does this...the ER doesn't, so I just took an imitrex. I'm crossing my fingers that I can make it through the weekend without another headache. I have read that many people have nausea issues with this treatment so I'm kind of anxious, but if It can break my headache cycles it's well worth it.
