i've had a buble on my shoulder for quite some time now (4-5 days) and i believed it was residue of a failled injection. it was painless to the touch. Yesterday i took a syringue and pinned in the bubble. to my surprise i was able to go very deep without feeling anything. i pulled the plunger, thick and very cloudy, white-yellow liquid filled the syringue, i pinned multiple times using multiple syringues to draw the pus and flush it down the toilet. pinning the buble using different angles, 4-5 times, i was able to draw 9 ml total!! now the buble no longer shows but im afraid the infection might progress again.
