3 days after the injection, I starting have signs of migraine with aura. I’ve never had this before. The first episode was on day 3 after the shot, 2nd episode was on Jan. 5th, 3rd episode on Jan 18th, and again today (4th episode) on Jan 21st. Episode of flashing lights and blurred vision in both eyes that last for 20 min. Some are accompanied by headaches. NEVER had this before in my life.
