"Abscess" is the more accepted spelling. I had an abscess in my left delt much bigger than what you're describing though. I too thought I could aspirate myself avoiding having to explain to the doctor why I was there at the ER. I took an 18 ga 20 cc syringe and proceeeded to aspirate my shoulder.
I made various entry points in an effort to remove all of the FOUL SMELLING brownish yellow pus at one point piercing a vein which shot blood all over my night stand, wall, carpet, lamp, bed etc.....upon stopping the blood, I began "milking" my shoulder forcing more and more crap out of me through the needle holes. Firrst of all, that crap was THE worst smelling shit I've EVER come across! Secondly, in less than one hour after my "home surgery" I had a fever of OVER 104 degrees and felt REAL bad!
My wife took me tto the hospital and the "fun" began, numerous blood tests, infectious disease doctors, surgeon, pulmonary specialiist, cardiologist oh yeah it was fun!
The infection had entered my blood stream and now my blood was infected, I was coughing up blood, having trouble maintaining blood/oxygen saturation above 80% and after a echocardiogram they believed the infection was also on my heart valves! They called it "vegetation".
Long story short, they needed to operate first thing in the morning, cutting my shoulder all the way to the bone chasing the infection. They left the incision open to heal from the inside out, I have pictures, but they truly ARE grotesque! Post surgery, they're hoping the infection isn't in the bone as it would take over a YEAR to recover from! I had a sonogramm done from the inside via my esophogus which revealed NO infection in my heart, thank GOD.
7 Days on Morphine every 4 hours, MASSIVE amounts of IV Zyvox (Extremely strong/expensive anti-biotics) and a HUGE open incision left to heal slowly.
All of this is NOT to mention the fact that I also got a visit from the nice folks in the "chemical dependancy" department extolling the virtues of detox to me and offering me to enter into a 12 step type program! My wife is stressed out, my kids aren't talking to me!
DON'T attempt to drain it!!!!!!!!!!!!!!!!!!!!!!!!!!
