i have a staff infection ( i think )

my left glute had a painful lump in it and it kind of pretruded so i stopped shooting there but i shot there the other day and tried to avoid the lump but i looked at it today and my lrft cheek is huge is it going to get worse if i do nothing now i want to avoid doing anything to it until my cycle is over which wont be for another 4 weeks but im going to the doctor on monday and im goiong to see what he says and i might as well get some blood work done

is it red, warm, or oozing?? also it's a staph infection and you wouldn't know that until the c/s comes back ;) Good call on the doc though, could be an abcess
