Should i switch to a different antibiotic for an ear infection if this one isn't working?

Ear infection: It is not a good idea to treat infections without a diagnosis--and a doctor--managing it. Many folks find some "old" antibiotics laying around and take them for what they feel is their diagnosis. Then for whatever reason if they don't get better, they try to switch, again without a good exam and a diagnosis. Lots of things cause ear pain, and antibiotics aren't the answer for all.
