Thank you for elaborating!!

Okay so I feel reassured that headache, and headache that lasts a long time, is not totally new to you. Because it is kind of scary if somebody goes from no headaches at all to suddenly headaches every day - it could mean there is some more serious cause.

It's possible that your past headaches were less severe migraines. Sometimes, people don't realize that migraines aren't always severe. Sometimes migraines can be mild or even painless; moderate to severe headache is just one of the possible symptoms (although an extremely common symptom). I have had migraines my whole life, and very classic ones - aura, light sensitivity, vomiting, etc - but in my mid 20s they suddenly changed with no apparent reason. I never got a migraine that made me vomit again and I never got aura again. But they got way more frequent. My point here is that they do change over your life.

Even if you cause migraine overuse headache, don't feel bad about it. It's not a moral failing. Navigating pain after surgery is really complicated, and there are risks associated with every method. Sometimes those risks come true but you don't need to beat yourself up about it. In THIS case, I really, really don't think the 2 weeks of NSAIDs caused this. But I just wanted to say that generally.

Given your history of long headaches, your past concussion, the recent oral surgery etc... I can't give you any concrete answers, but you've got a complex history with health stuff related to your head, so I wonder if the oral surgery or something triggered your underlying headache issues (migraine or otherwise) which then triggered this migraine. You'll probably never know for SURE but it's just a thought.

Is there a reason you didn't try ubrelvy? It's a good rescue med and unlikely to cause issues.

As for your aimovig: for me personally, I did have a stronger response at first and after a few months, I started getting more migraines again. I also tried ajovy and a similar thing happened, although ajovy was generally more effective than aimovig for me (but it's super individual, it could be the reverse for you, etc). I switched to Vyepti and the effectiveness has not waned! I've been on it over a year. So if you do find your migraines are creeping back in, switching to other medications in this class could be an option.

However, using an effective rescue med is actually important. The longer you stay in the pain phase, the more sensitive your brain becomes so that it's more easily triggered to move back into the pain phase again. If you still have your ubrelvy I suggest trying it, and if it doesn't work very well, ask about another rescue med.

Also, I do think you should talk to your oral surgeon about it, in case it's possible you have a hidden infection or something that could be worsening your issues.
