Just to break this down a little...the vision changes as well as the 'lightning bolt' are your "prodrome." Basically it is the 'warning' that something (a headache/migraine) is on its way. Generally, a few hours to a day or so before the headache arrives.
Next is what they call the "aura" (only some people have this) and yours sounds like the "lightning bolt" objects which is followed by head pain then the final stage "postdrome" which is the icky, tired, achy feeling left after the pain subsides.
The tingling or numbness is common with migraines as well as the sensitivity to light.
I am not saying that its FOR SURE migraines (Im not a doctor) but your symptoms make it seem possible. I would talk to your doctor about a preventative medication that can keep you from having these episodes if they are happening often. If they are just once in a while an acute medication will help end the head pain and accompanying symptoms.
I hope that helps some in understanding a little more about what's going on.
Please let us know how things go!
