Welcome to the Migraine and Headaches Forum! This forum is for questions and support regarding migraine and headache issues such as: abdominal
migraines, headaches caused by allergies, cluster headaches,
headaches, headaches in children, migraine headaches, sinus headaches, tension headaches, visual disturbances.
I think you might have to suffer through the migraines prior to your surgery, unless someone else knows for sure and can tell you that it's safe to do so.
Sorry, I see you mentioned headaches, but didn't specify which kind. I assumed it was migraine, as I have migraines myself, and I've heard of treating them with Relpax.
