Sore piercing

I got a helix piercing about a month ago, and it stopped being sore a couple of days later, which I was super excited about lol.

But for the last couple of weeks, it has gotten really sore again. I can’t touch it without it feeling sore.

There’s no keloid, no crust or ooze or anything visibly wrong with it.

What can I do to make sure it’s not getting infected even though there are no visible signs of infection? And any tips to help the ease the soreness?
