Cohesion,
I have had migraines and probably other types of headaches for almost ten years now. I understand what you are dealing with and know how hard it is. I know you are just doing what you have to do to get through school but it does seem like there has to be a better way. I have been to dozens of doctors and tried all sorts of things as well. I have been told the same thing about rebound and have gotten off all medicine for 6 months to prove that I don't have rebound. I like you still had the darn headaches--I was just miserable without any relief. I cannot take any kind of narcotics because of side effects, but I take Esgic-plus--it is the only thing that works, but again, when you have it everyday and all the time, that's not much help because I try to take it 3-4 times a week to avoid the possibility of rebound. I agree that you need to find a really good primary care doctor. My primary care doctor has tested me for more things and seems to believe my pain more than any of the neurologists or migraine specialists or pain management doctors I've been to. I also cannot take the triptans (Imitrex, etc.) or the anti-seizure medicines. I know the other post said that it is not possible to have gone through all of the drugs, but my neurologist actuallly agreed and said that I have been through the list. Due to other medical problems and side effects, there is not a preventive I can take and I have only found two things that I can safely take for the pain during an attack--Esgic and Midrin.
Here are some things that I have tried and maybe they could be of help to you. You may have already tried these things, but I thought I would just give you what I have learned from experience just in case it might help:
-first, just the obvious, which I'm sure you've done- getting rid of all migraine trigger foods, keeping regular sleep schedule, etc.
-acupuncture- Didn't help me that much, if at all , but others claim it does.
-chiropractor- didn't help me much.
-osteopathic doctor- This probably helped the most. They can do manipulation techniques to better align you and you actually do feel better. My doctor also does trigger point injections and these will nearly everytime knock the headache out for the day, sometimes into the next day. He says it is supposed to last 1-2 weeks and does for his other patients. But it is a good relief without having to take medicine because the shots he gives are natural...Look for a good osteopathic doctor who does this. They also do other treatments--acupuncture, acupressure, herbal supplements, etc. I had some of these shots from my neurologist (without the natural stuff) and my head was numb for a few hours and the headache went away but then my head was SORE the next day or two, but I haven't had that problem with the natural shots without the steroid.
-Lidocaine nasal spray- it is supposed to numb up a nerve up in your nose that is supposed to help. The trick is getting it to the right place. Sometimes it works. Ask your doctor to try this--it is cheap.
-Migrastick-this is something you can buy at a natural store or online and it is peppermint and lavendar in a little tube and you just apply it to your head. I like this not for the smell but because it cools my head and makes it feel better. I pretty much have an ice pack strapped to my head when I'm at home, but when you can't do that when you have to be somewhere this is a good subsitute because it will cool your head.
-Anti-nausea medicine will help with your headache pain as well as the nausea when you are really hurting and help you sleep without any rebound effect. Ask your doctor for this.
-Oxygen- breathing pure oxygen is supposed to help, especially with the sharp ice-pick sort of headaches. I have found that it won't exactly kill the pain the way others have described but it does help you to relax some and feel a little better and sometimes that is worth a lot.
-Botox injections- I haven't tried yet because of my side effects issue and the new FDA warnings, but some claim it works.
I hope that something out of this long post helps. I know how hard it is, but hang in there and keep searching for something that works for you. I'm sure you will find a doctor that can give you something to get through this without having to rely on constantly taking narcotics. I really believe that we will not be like this forever. I have had relatives that went through this and one day the headaches just went away--not because they did anything different. Good luck to you!
