Hello, So A Few Weeks Ago I Went To An

Hello,
So a few weeks ago I went to an ear specialist because I had a cartilage ear piercing that had gotten infected. The cartilage is severely damaged on the outer part of my ear and my doctor said it would take months to heal. I was put on antibiotics and everything was fine and dandy for a few weeks. It was only about four days ago that my ear was red, hot and throbbing. I called my doctor and he put me on the same strain of antibiotics that I was previously using when I first got the infection. The same hot redness happened today after I took off my headphones and my headphones are the kind that go on the ear (similar to Beats headphones). I used my headphones three times today and each time I took them off the redness came for a little while and then it went away. Could it be that my headphones are putting too much strain on my ear and that is why it is getting hot and red?
