I had a oral surgery 5 days ago which causedan infection. they have me in antibiotics but the pain has now spread to my ear. what should i do?

Follow up : With the treating doctor asap. It's impossible to diagnose or recommend treatment over the internet without an examination, knowledge of the procedure performed, the circumstances pre-surgical, medications ... Hope this helps.

See your Doc: You may have a dry socket ( alveolar osteitis) depending on what kind of surgery you had. If it was a lower molar or wisdom tooth this is most likely. You need to contact your oral surgeon so they can take proper care of you.
