Why do I keep having a shimmering circle in the center of my field of vision when I get home after exercise, and why, strangest of all, does this only happen when I exercise at the coast, never anywhere else? I never have headache migraines.

That does sound like a migraine.

 

I get migraines a lot, and get the shimmering you described. For me it's a sign that a migraine headache is coming. Do you get any other symptoms, like increased sensitivity to light or sound, or nausea? Even if you don't, I think it would still be a migraine, because I know people who only get the shimmering.

 

Also physical stress is a trigger for migraines, so that would explain why you get it after exersice.

 

Changes in weather and humidity can be a trigger, so that could explain the coast bit. Also there are some links between migraines and warm winds, and also certain odours can bring on a migraine. Maybe the salt smell?

 

I'd say the combination between physical stress (excercise) and the salt smell.

It's called a phantom migraine if I Remember correctly. Like other migraines theres not a whole lot you can do but figure out exactly what triggers your's and avoiding those things.
