I have them one a week on average. I have consulted a doctor about it once, they just kind of dismissed it and said it was stress. It is not stress.
it lasts about fifteen minutes maybe a half hour before the numbness starts to go away and I start to be able to focus again, it takes about an hour or longer for the dizziness to completely pass.
I have tried to rack my brain about what causes this, I can't come up with anything that is common background among the attacks, it seems random to me.
I think it's important to mention that I do have hypothyroidism and hashimotos
