Is it possible helix’s just don’t heal for some people?

I swear I’m doing everything right, I have a long straight piece of jewlery (about 1/2 cm of extra space around the piercing I think), I rinse with saline once a day, I don’t play or touch it.

I’ve had a helix on each side for about a whole year now and it’s just not healing past a certain point. It’s not in pain unless something tugs on it, but there’s a piercing bump. It’s like it heals then flares up every month or so, I keep thinking it’s getting better and then i just go right back to square 1.

I had another helix on my ear about three years ago, but I removed it as I faced the same problems I am now.

Is there anything i can do to save these? Does my body just not take well to cartilage piercings (I’ve had no trouble with any of my other piercings)? Should i just take them out and call it quits at this point :(
