I had my first SS 3 years ago at 64.
All events have been triggered by glare so I have been trying various measures to reduce the stimulus and other factors which may bring it on. What I personally find unique to the onset is that it is not just bright light but the orientation of the glare AND contrast with background. For example, sitting in a dark room watching a presentation with a shimmer of sunlight reflecting off the window sill may cause the SS. For me, it seems that the orientation is also a factor since horizontal glare seems to be the main trigger vs. spot or vertical glare. I suspect this creates the initial stimulus overload to start the CSD wave propagation through the visual cortex. Has anyone else noticed a unique pattern of light causing this? I've had 3 episodes in a week after being symptom free for 2 months. I also suspect the lower angle of the sun in Spring and Autumn may play into this by creating the horizontal glare and light polarization. Besides the typical SS symptoms, I also get nausea, a hangover feeling, and sometimes a mild headache.
I just joined the group and was hoping to find a way to stop the SS before it gets going. I thought the neck manipulation and yogic breathing may be a help and will try this.
I do not take any medications for this. The doctor recommended Excedrin ( Aspirin, Acetaminophen, Caffeine). I thought this was pretty lame considering caffeine may also exacerbate the onset. I also saw some comments on another site which stated Cannabis may stop the SS and resulting symptoms.
ANy suggestions are much appreciated.
