First and foremost I am sorry that you are experiencing this. I have had covid twice. The first time I got it I don't with long covid for over a year I was in the hospital five times, I am making a very very long story short. The second time I got covid about 6 months ago, somehow it kicked out that long covid. Since the first time I had covid I get those electrical shock feelings in my temple in my head. Always the left side. I have gone to the doctors for it, my doctor told me to go to the eye doctor. I tried to explain it to my eye doctor, unfortunately I did not have my regular doctor that day, she tried to tell me it was shingles, I told her it most certainly was not shingles but it's not a sensation feeling it's a pain in my head. I still get these, sometimes it scares me cuz it reminds me of what an aneurysm may feel like. But I have had to accept them I don't know what they are I don't know how to get rid of them and I'm sick of being afraid that I'm going to drop whenever I feel that pain. I understand that electrical shock feeling. I hope at some point they will get to the bottom of all these crazy symptoms that we get after covid and during. Take care of yourself and hang in there.
