I had pretty bad ocular/retinal migraines in my adolescent years. My left eye would slowly go blind, then within 30 minutes I would have a debilitating headache with nausea and extreme sensory sensitivity. Nowadays about 3 or so years since the last migraine attack that had that regular pattern, I still have some issues that might be lingering migraine symptoms
1. Striped patterns 'glitch out' and make me feel sick
2. I have after image in my vision, sometimes worse than other times
3. Sometimes I have the feeling like there are bands overlaying my vision, even though they're not clearly there, it is somehow still noticeable. It's hard to explain that one...
4. Sometimes I can see flashes/light briefly pop in to my vision before disappearing. Sometimes it is so quick I have to assess if I imagined it! haha
So my two questions are: Does anybody know if it's possible to have these visual disturbances without any actual headache? And are those migraines I had in adolescence foreshadowing to a bigger neurological problem or is that just my health anxiety talking?
