Hi I am a former IV drug user, I've been clean almost thirty days. In the past I've had bacterial pnemonia from IV drug use. I'm starting to experiances the symptoms again by don't know if it's that. About 2 months ago I had abrasions all over my legs that were swollen and filled with puss, it took a month to heal, now I'm having some chest pain, fluttering and sharp pains on and off under both sides of my rib cages, random pains throughout my body, lower back pain on the leg side only, strong smell in urine, lightheadiness, confusion, blurred vision, pulse 120bpm, cold skin but sweating and a feeling of severe anxiety, could this be pnemonia caused by staphococis bacteria considering the abrasions on my legs that took so long to heal, also could it of caused septic shock?
