Weird swelling after 3 years (Photo)

Hello, I had my otoplasty done 3 years ago (in 2020) where my ears were pinned back and an anti-helix was formed. A few days ago, I noticed a weird bludging on the anti-helix, and i can’t tell why it is there. I recall experiencing pain sometimes when i sleep on that side but it usually resolves immediately if i change the position. normally It doesn’t pain if i would touch or press it the area. Any advice would be much appreciated!
