covid vaccine and migraine changes

Hi,

I'm 43 and usually have 1-2 migraines a week, a pattern which has been relatively steady at least for the past 10 years. The most I've been without an event is something like 2 weeks which happens very rarely, once in a year or so.

Now for the strange thing. On the morning of February 1st I took the 3rd dose of the pfizer covid vaccine. That evening I had a migraine which went away after taking a zomig, as is usual.

Until this morning I haven't had another event. It has been nearly 4 weeks without pain, which is unheard of for me. Plus, during this time I've occasionally drank wine and spicy food (which are both known triggers for me).

Now, this morning I was working in the garden and with the wind got some soil dust into my eyes. This triggered a visual aura (its not the first time that stuff getting into my eyes trigger a scotoma). I waited for it to go away, already expecting for the pain to start afterwards. However, it never got to develop into a full fledged migraine. If I sneeze, I feel a slight pain around the eye where the migraine usually hits worse, but that's it. Its as if the migraine is there but there is no pain.. this has never happened to me before.

This being said, the vaccine can be just a freaky coincidence, and I was surprised that searching on the forum it seems most people reported the opposite (an uptick in migraine events after the vaccine).

I was curious if anyone had a similar experience or a possible explanation for this change in pattern/behavior for the migraine.

Thanks
