i am not sure what ca-mrsa is but i have had mrsa in every part of my body and know that after it has gone silent you are still a carrier it can come back. i had mrsa for 2 years. i had several hospitalizations which included vancomyacin a broad spectrum antibiotic it did not get rid of it. it was not until i met a doctor that had me start a new hygiene regimen which included bleach baths ( 1 capful in a hot bath ) and hybacleanse washes which is a antimicrobial killer that you can pick up at several drug stores. additionally keep your nails short since it thrives under your nails it also lives in the sinuses. i recommend a saline wash several times a week. also white towels only bleach after each use. i followed the above for about a year and it finally went away it has been 4 years since i have had any symptoms. good luck.
if you had ca-mrsa and were treated can you get it again without coming into contact with the bacteria again?
