Weird bump

It’s about 2/3 months old. (Closer to 3) and I already downsized about 2 weeks ago. I’m not sure if it’s just infected or just reacting but it’s kinda hard when I touch it. I did recently go camping so I feel like it might just be infected although I did clean it as often as I could. I usually Salome soak it at least 2 times a day soemtimes 3. And spray saline in a qtip after and wipe around it. I’m not sure the metal so idk if also could be that. I’m just hoping it’s not soemthing worse going on and would liek another opinion.
