I was just reading that some lupies suffer from seizures at some time or another. I've never had a problem with seizures myself, but I can see how that can be worrisome for some lupies out there.
According to the article I read at Reuters, hydroxychloroquine helps treat seizures. The article also states that seizures are seen early on in lupus diagnosis.
I mention it so that lupies know that they aren't alone, and that there are plenty lupies going through the same thing. Hopefully, you're being treated and the medication is helping alleviate the symptoms a bit.
Take care and live lupie!
