Weird Bump with Water Inside

Hi, this thing appeared on my hand more than a week ago and idk what it is and how I got it. I'm 20(M) and I was recently bitten by a cat (about 48 days ago) and I recieved 3 doses of anti rabies already. I just wanna know what this is and if it's related to my previous encounter. I've opened this wound 2 times now and each time there's liquid coming out. It doesn't hurt when I pinch it and I think it grew a little bit and then stopped. Idk what it is and the AI said it's probably a keloid but I can't trust AIs lol so I'm here. I've been anxious about this for days now. Any idea what this could possibly be? Thanks!
