I've some weird type of a migraine which sometimes I'm not able to read or speak properly in English or Spanish (Always one of these combinations, fortunately). It's like I forgot how the words are "divided by syllables" and I'm not able to read or speak properly. Fortunately, it's for a few minutes and I got a migraine just one or two times a year. I went to the doctor and he said it's not dangerous and there is nothing to do. Some people have migraines every week, even in the worst cases with vision loss so my problem is nothing compared to that.
