Migraine is not something I’ve suffered from in 67 years of life, but two family members have, so I am aware of symptoms as described.
About a month ago and for the third time in total, today I am suffering the “jagged vision” symptom – still no head pain or nausea on any occasion. And so far not felt the need to take any aspirin or paracetemol.
This post is just to capture a description of the visual symptom.
Fixed area peripheral top and left, with one branch towards the centre from the left. One edge of that branch fixed and highly defined jagged line. The fill below and outside that edge is the classic twinkling jagged shards of glass or ice. Essentially shades of grey, black and white but with the refraction rainbow fringe colours of thin films, overlapping and of variable thickness. I say “fixed” in the sense that whilst the pattern of jagged shards is in constant motion, on a half to one second period, that jagged edge sticks relative to my field of view. If I fix view on a focal point on the wall in front of me the jagged line is absolutely fixed. I get the feeling it’s more associated with the left eye, but it’s clearly in the mental / cortical representation of the field of view.
Subsiding now after about 20 minutes after a few minutes where the intensity directly interfered with my ability to see what reality was in the affected area in front of me. All absolutely classic I see now as I Google the symptoms.
(Where’s a pen when you need one, I could draw what I’m describing, for future reference.)
This is just a libary pic. Same idea, different geometry / distribution, more peripheral except for one jagged line from left to centre in my case, and much mor intense colours than my experience:
Oh, oh. Following day 13th March 2023 symptoms again. Different geometry, and smaller size, but exactly the same pattern. Small hard, fixed, jagged curlicue, lower, mid-right – with the jangly shards hanging off it.
Time for a stroll on the beach. Done. Gone.
