For the past 18 months, I’ve been getting migraines when I hear music in small spaces (cars, headphones, my office). Volume doesn’t seem to be a factor. I have no problem with loud concerts, music in bars, etc., and it doesn’t seem to matter what type of music I listen to. I just can’t handle any music in small spaces. I can’t find anything on the net to explain it or help me figure out how to deal with this. Does anyone have suggestions?
