One year old tragus piercing

Is it possible that somebody's body just can't have cartilage piercings??

I pierced my tragus in October last year, but still quite often I get lumps on it and sometimes even puss is coming out of it. I treat it with saline solution and some ointment my piercer recommended and it goes away in 2-3 days. But it bothers me that it keeps coming back 🙄 I think the main reasons are sleeping on it and wearing a mask, so sometimes I pull on it by accident... My piercer said it's not uncommon but it's getting on my nerves! Does anyone have similair experience and what did you do to make your tragus less "angry" (that's what I call it as a joke 😂)? Or should I just give up, say I'm not able to have a cartilage piercing and take it out? 😭
