For the last couple years I've been having issues going into some convenience stores where their air compressors or heat pumps are causing dizziness. My head will just start pounding so I have to get in and get out as quick as possible. Once I exit the store the issue stops, however, several minutes later I will have sort of a callidoscope starburst in my periferal vision. Appears on the left side only, I can close my eyes and it is still there, just more colorful. Yesterday this same thing happened to a much lesser degree at Wal-Mart, so places where it hasn't happened it is now starting to happen so that has triggered my "worry meter".
I'm healthy, 42 year old male. BP stays around 118/78, pulse is normal, on no medications. Any ideas would be greatly appreciated!
