of course you need to get it checked out. i am surprised that it took you a year to get to this point. there are many many causes of ear pain including many causes that do not involve the ear itself. it is going to take a thorough systemic diagnostic work-up to get to the bottom of this year-long issue.
severe pain in left ear. randomly i get pretty severe pain in my left ear. when looking straight its pretty painful but when i turn my head to the left it becomes an almost unbearable pain. it seems to come on at complete random and has been happening for about a year. the pain usually only lasts for a few hours but its happening often enough now that its starting to make me wonder if there is something wrong that i need to get checked out.
