Keliod?! Navel infection? or just scar tissue?

so I got my belly on peirced in the beggining of august. I've been taking care of it, doing the seasalt soaks and dial soap cleanining like they said. But about a month ago (january) the peircing started feeling a little sore and swollen so i figured it was still healing and kept doing the soaks and cleaning, then there was a week where it hurt just to touch it and was really sore so I took the bar out and kinda squeezed it and all this puss and blood came out. after that the peircing felt better and for the rest of the week i would take out the bar and clean the area until more of the junk in there was out. so lets get to the point, ever since that week my peircings felt kinda weird. almost like theres scar tissue in the inside around the bar. maybe i'm just getting fat and its just my fatness going around the bar? could it be a keloid? it feels almost like a little ball if i pinch the top and bottom holes of the peircing? after googling for my answer i've freaked myself out and if your wondering "why the hell havent you gone to see the piercer?" i havent had the time with school and work :[ help?
