I had to stop using Aimovig suddenly after being on it for about a year because my health insurance stopped covering it. I was fine for the first few weeks but now I'm on my eighth day in a row of constant headaches that feel different from my usual migraines. I didn't have headaches like this before I started the Aimovig. I am wondering if this is just my system adjusting to not being on Aimovig? Has anyone else who stopped using Aimovig had rebound headaches? If so, how long did they last, and what did you do to treat them? Nothing I've tried seems to work, and I'm getting desperate.
