I am on my third week injecting sustanon 250....I did my first injection in my right shoulder, the second in my left shoulder, and this last one 3 days ago in my right shoulder again...I have knottting again in my muscles in my shoulder, but what is worrying me is the small firm lump under my shoulder, but just above my bicep. ...Can someone please help me with this..I am new at this, and have no clue what it could be..or if this is normal.....also, the pain is pretty bad too.
Thanks..
