I just learned i have mrsa in my kidneys, what my treatment options? antibiotics have not helped.

See an ID doctor: This should be managed by an infectious diseases expert. They may wish to obtain assistance from a urologist or nephrologist or both, but the choice of antibiotics will depend upon the sensitivity of the MRSA isolated, your underlying medical conditions, and your allergy history. If antibiotics alone are not effective you may need some form of surgery. See someone asap.
