Maybe go back to one of the docs that diagnosed osteomyelitis for treatment?
Understand that they will want to start with Augmentin or Penicillin unless they have done a culture to identify a specific bacteria.

Also, often when treating infections, there is a treatment protocol called "step up" where they try drugs in a certain order, and if you refuse what they offer, they may decide not to treat you. This is to keep the strongest drugs "in reserve" for the most resistant infections, as superbugs due to indiscriminately used antibiotics are getting tougher all the time.

There may also be something else in your health history that makes the reluctant to give it such as reaction to another antibiotic, kidney or liver issues, or diabetes or something else.

SO what is the bottom line? Getting care is a two-way street. If you want to beat this thing, whatever it is, the doctors expect you to work with them - sometimes that means starting with their recommended treatment .and moving on if it doesn't work. And not going out on your own and adding other drugs to the regimen...

Are you willing to go back to one of the original doctor s who diagnosed that and try.?
Wouldn't that be better than continuing to suffer year after year?
