These flashing jagged lines move across my visual field for about 30 minutes at a time.  I had this occur 6 times in 10 days then nothing for 3 weeks.  Then I've had one a week for the last two weeks.  I don't get a headache following this.  I do, however, have a stiff neck, jaw and tooth pain.  I also have lots of knots around my shoulder blade on the same side.  I have been more stressed that usual.  Does anyone else have symptoms like these?  What is this considered?  My family doctor tells me they are migraines with aura - even though there is no headache.  My chiropractor doesn't label them, just adjusts me and takes notes on when they occur.  He also started doing acupuncture on me.  While the needles are in, it seems to help.  But, the effects don't last long.
