This is worth the inconvenience of going to the doctor because it can have different causes, and it’s a waste of time and money to treat the wrong thing.
Both my husband and I have had it. He was taught the Epley maneuver. I was given medicine (it was several years ago, and I don’t remember what kind). So perhaps we had different types. In both cases, it went away – for me within a couple of days, for him within a couple of weeks.
