Need to visit a doctor

Hospitals have big lots. If you have a GPS use the closest hospital feature. Otherwise call from any truck stop to find out where they are. No sense putting it off.

I can be helpful to determine if it is an inner ear infection or external such as basic swimmer's ear.

Internal is generally duller and accompanied by cold symptoms or fever which is the hallmark of infection. It often affects both ears.

If the ear hurts by manipulating it, pulling it to and fro, pushing in the middle ear flap covering the canal, or painful to touch the face in front of the ear it is likely external. This is less serious, could self-resolve, and you could benefit from simple white vinegar or alcohol in the ear.

If it is internal, if the area behind the ear becomes red, then the infection is spreading outward. Then it would share some of the symptoms of the external as well. An inner ear infection needs treatment asap.
