I have inflamation in my ear causing pain where my ear attaches to my scull, causing migraines.

It is not an ear infection. It is inflamed from my ear popping when I bit down on an almond when I had a bronchial infection. I finished my antibiotic but my outside of my ear still hurts where it attaches to my skull causing migraines. The inside doesn’t hurt. The prescription for the anti-inflammatory drops cost $79. I was wondering if there was something I could do home remedy to help. Thank you, Kelly
