I started having lightning flashes in eye lst night. Called to make apt with eye doctor and cant get in until monday...that is 3 days from now...everything i have read says to go imediately..should i go to er, i have a headache, not as bad as a migrane, but it is starting to scare me. especially after all that i have read...they all say go right away to dr, dont know if that means immediately or wait the 3 days .
