Staphylococcus. Another iv treatment!

I Got This Staph Infection From Someone In Office In 2015. He Had Left Leg Abnormality. I Sat On His Chair I Got The Same Thing On Mime Leg . It Was Filled With Deadly Pus. Very Very Painful.  Then I Was In Hospital For 10 Days. It Was Found To Be Staphylococcus Aureus. It Cleared The Infection.  I Was In Walking Condition  But After That I Keep Getting Boils On Bum Region  Mostly.  Its Very Painful. Syarts With A Dot N Then Covers Upto 4 5 Inches Circumference Until It Becomes Full Of Blood N Pus. Since 2015, I Am Living A Very Painful Life. It Sucks Away All Energy N I Go In A State Of Shock. They Treated With Vancomycin Or Linozelid IV. Not Sure and operated to remove pus under full anesthesia Should I Go For Another IV Treatment
