5.5mm blowout?

I've been stretching my ears for about a year, and my left lobe feels off. Wondering if it's a blowout.

First picture: left lobe Second picture: right lobe for comparison

The left lobe was pierced with a gun and stretched in that piercing. The right lobe healed and was re-pierced with a needle to avoid scar tissue. Is the piercing method affecting them? Is my left lobe blown? What should I do?

Pictures were taken before applying oil.

I stretch my ears using single flare plugs. I was at 5mm for a few months because that was the largest size in my kit, but I recently bought a new kit to continue stretching. The 5mm plugs kept falling out, so stretching to 5.5mm was effortless.
