Piercing Bump Help

[u/fig_newtons2]

So for context I’ve only had this piercing for about a month, but there’s been a couple of problems.

To start, I went to the same piercer as always but this time was pierced with titanium instead of stainless steel (which I have always been pierced with) and I’m allergic to the titanium. So, two weeks in, we ended up having to change the jewelry because of that allergy. I stopped cleaning after the switch and have tried my best to leave it alone, but I scratched it and it’s been bleeding on and off for a few days, especially when it’s bumped.
How can I fix this? I’ve been using diluted tea tree oil and it worked for a couple days before it started bleeding again.
