Richie,

I am so sorry the injections didn't help you. I think that is what is so weird about having ON. The docs originally diagnosed me with ON but when they saw the cervical spine MRI they changed that diagnosis to Cervicogenic headaches with variant migraines. I feel blessed in a sense because the culprit was eventually found but it took a good 3 years. But I also know ON can be muscular in nature and all kinds of other things. I hope the Botox works for you as it did my friend. Let us know if it helps.
