I have no doubt you are fustrated, especially since they told you to got to Sloan. That institute does have a good reputation. I sincerely hope Bryanna can suggest something. I do know that Levaquin is one of the best antibiotics on the market. It is used to treat very stubborn infections. I will be thinking about you, and hoping that a resolution can be found, where you will not get a repeat infection, and can heal. ginnie
