I sketched a "migraine aura" I get once every two weeks to a month. Often they preceed a headache, but I don't get a follow-up headache. They are quite bothersome when trying to focus my eyes on anything. I just sit back and enjoy the show of flashing colorful triangles that usually migrate out from my center of focus to the edges of the field of vision and disappear in about 10 to 20 minutes. Below are two attempts at capturing the auras. They don't do justice to the flashing. | |
