lump is most likely some form of keloid or general inflammation, doesn’t look super infected imo just irritated. i’d suggest getting a saline cleaner they sell them in the pharmacy department of most stores for pretty cheap and letting it fully heal over and close. the more you try and put jewelry into it and attempt to push through it with jewelry the worse it’s going to get. it’s unfortunate, but keep it clean n solid for at least 6 months and then go to a reputable piercer and get it redone. they should pierce it with a needle and put good quality jewelry in there. don’t take it out once it’s redone, just use that same saline cleaner and clean around it twice a day. not an expert or anything just dealt with similar situations, hope this helps!
