lady:
i'm a systemic masto. i don't get anything like what your describing but i get pain around my eyes occasionally. i use pataday & it's great for claming down mast cells. don't know if it would work on yours, by the way it's a script.

I went through having lightening bolt flashes in the sides of my eye when in the dark.  I went to a retinal eye doctor and had my eyes thoroughly checked out, which was the right thing to do.

This symptom could be something serious like the beginning of a retinal detachment, so only an eye doctor can truly evaluate you.

I turned out to be okay and was told that it was not uncommon for people of a certain age (ahem, I am over 60) to get these symptoms, and that if no other problem is present, it will eventually dissipate.

 My lightening flashes have stopped.  In my case, it was part of a normal aging process.

Again, this can be something serious and I suggest calling an eye doctor, preferably a retinal specialist, and telling them of your problem so that they can set up an appointment soon.  That is the only way you can know for sure what your problem is.

Futurehope, I did have my retina's checked and they looked fine. But now that I have been diagnosed, I am going to look for an opthamologist who might be familiar with MC disease. That will probably be like looking for a needle in a haystack though.   Thank you again!
