What is the best remedy for left ear pain.i been having this pain for the past few days, over the counter ear drops not working boiled olive oil with fresh garlic cloves, seems to work for few hours then pain returns?

Basics: Common ear pain can originate from the canal (swimmers) or from the middle ear from infection. Ear drops might help a canal infection & oil concoctions might give transient relief by coming in contact with the ear drum. Proper assessment of the cause & treatment will require that the eardrum be examined.Some such infections self heal but can lead to complications over time.
