hi there i'm 19 and when i was younger i suffered from migrane with auras and nausea. i had one in March 2017 and had none until October 2018. I Had an aura that started off as like a light/ blindspot that got bigger and went away within 25 mins. The next day i felt nauseous. However a couple of weeks after this I had a short bout of double vision that lasted a minute - it was frightening and two days later i went to the optician and he checked my eye muscles backs of the eyes eg and said there was nothing wrong and that it was due to blood being pumped around the body(too slowly) like when you stand up to quick. But two weeks ago i had another aura that again went away within 25 mins and i felt sick after but that was more or less it. But ever since this, i have felt weird. A few days after this i kept feeling like i was going to experience a blindspot but never did. My left arm has felt disconnected on and off but not numb. And now my corner of my left eye feels weird like as if I cant fully see out of it but I can. - now when i take my glasses off and close my right eye, my left eye is a bit blurry. I'm longsighted. I have booked an appt with my GP but it's in over a months time. I dont want to go back to my optician because it'll most likely be nothing serious but I'm scared it is. I can't sleep and my dad even says I'm not myself. So let's get this short lol even though I'm NOT experiencing an aura it feels like there's something 'left' from the aura. I have a terrible fear of going blind and this doesn't help. Sorry for the long post -any advice? Is this something you have experienced? Thanks
An optician is not medically trained, if you are worried see an ophtalmologist. But the fact your having issues with your left arm makes me think you may need to see a neurologist, have you seen one already about your migraines?
Thank you for replying - i went to the doctor in the past and it wasn’t serious but probably is due to stress/ eating too much chocolate e.g but couldn’t find the specific cause. When i was younger i felt lightheaded/ dizzy a lot but the doctor performed reflex methods on me and no cause was found and my blood pressure is fine. I’m scared - my parents probably wouldn’t take it serious that i should go to a neurologist 
i think i might suffer from depersonalisation due to anxiety but this doesn’t feel like it
Keep a diary of your symptoms, see if there is there is a pattern. Like is it worse every month or after eating something or drinking alcohol or maybe after being in front of a screen or exercising. Try and get a good amount of sleep if you can, sleep is so important for healing, if you have anything wrong with you, it is always made worse if you don’t get enough sleep.
Tuve una experiencia similar. Mi ojo izquierdo se sentía raro, me salían puntos negros y luego una luz brillante, pero luego se convirtió en una sensación de cortina en el lado exterior de mi ojo. Fui a mi oftalmólogo, quien sería el experto en esto. Después de examinar mi ojo, estaba muy preocupado. Me dijo que viera inmediatamente a este cirujano de ojos. Él programó la cita. Era más tarde en la noche, como a las 7:30 o 8, pero fui y fui examinado por un hombre que en realidad tocó mi globo ocular. De todos modos, se programó la cirugía para dos días después. Se determinó que tenía una retina desgarrada. Si lo hubiera dejado pasar, sí, podría haberme quedado ciego. Eso fue hace como 1 o 2 años. De esa cirugía, supongo que es normal luego tener cataratas en ese ojo. Iré en dos días para la cirugía de cataratas. Ahora, la visión de mi ojo ha empeorado desde la cirugía. Dicen que es muy común después de la cirugía de retina desgarrada tener cataratas. Estaré contento cuando termine porque últimamente he tenido terribles dolores de cabeza. No sé si eso está conectado o no.
