Cowgirl I might suggest that you have a partner on your runs.
The advice to see a Doctor is good, but until your are diagnoised I would be careful with intense exercise until you are cleared for it
I wont go into your medical history, but I will say my sister had a TIA and she ended up having to quit smoking
It sounds like lack of Oxygen to your brain that caused the disorientation, seeing as how it happenned when you were running
But.....a Doctor should give you a full medical examination to rule out ...diabetes ( both high and low blood sugar can cause disorientation, do you know what you blood sugar is?) TIA this is common esp if you have a chemical imbalance such as smoking would cause, or caffiene, ( did you take any hihg caffeine "energy drinks"?)
I am curious to see what the doctor says about these episodes, and he simply shrugs his shoulders and says "I dont know" then plz go get a 2nd opinion
In any case plz use some safety precautions when you go out running, ....ex. have a cell phone on you, have a partner with you, run in a public place in a well lit area where there are police nearby who can react quickly if you have an episode that is more severe than your previous ones.
And to answer your question...YES I have had similar episodes to this but I have known disease processes going on.....diabetes, Heart Disease, taking blood pressure meds, that tend to cause little epidodes
