I train in MMA (Mixed Martial Arts).
About 3 weeks back, I got my ear in a bind (headlock, probably, but it wasn't traumatic enough to make me think about it).
I went to a dermatologist, but they were not really sure what to do about this. My ear was drained, and I was given 10 days of antibiotics.
The ear is still sore and fills with fluid once a day.
I use a 22-gauge needle to pierce the skin once a day, and I draw out about 3cc of a blood/puss mixture like what they show in the video link (do not watch if you are squeamish): https://www.youtube.com/watch?v=e9093SAO13I
Looking up the treatment online, it just says to drain the ear:
Is there nothing else I can do?
In the pic below, I'm in the green shirt. You can see the swelling in my ear. It isn't huge, but it's there.
