What should i do about mrsa on my body i had tried multiple things it keeps going away and coming back on different spots on my body?

The body has a regular germ population on many surfaces that comes & goes. If yours includes MRSA it is commonly housed in your nasal passages. Using OTC antibiotic ointment 2x daily at the nasal entrance, taking baths several times weekly with a cup of bleach in the water & taking a PO anti-staph med can break the cycle of carriage. It is easy to re-acquire MRSA from the environment.
