A few days ago I shot 8mg of dilaudid. Right after injecting the D, a lump about the size of a nickel developed and was kind of sore. I have had this lump before but not as big and not as long. I am assuming I missed, it was red right after and the next day but today it wasn't red, and not sore anymore either. I did however feel a rush, just not quite as intense as it normally is. It also seems to have "risen up" a little. Will it go away, without me having to go to the ER?
