Does this sound like a belly piercing infection or keloid?

I got my belly pierced last wednesday tomorrow is gonna be a week that i have it. In between the jewlery in the middle the skin is really hard and it hurts, i get pains here and there its also red but i have no puss or crusts on it. i been cleaning it with h20 but i stopped and switched to sea salt soaks today. so what can this be??
