A bone infection especially with MRSA is a very serious condition. It requires extended treatment with specific antibiotics and possible surgery to decrease the load of infection. Many communities have medical care available for patients who cannot afford it. Check to see if there is a community health clinic in your area. Some states have programs for people without medical insurance. He may be eligible for Medicaid. Check on all these things for coverage. In the meantime, he can go to an emergency room and start treatment. They also might be able to refer him to places that provide coverage for indigent people. An ER by law is not allowed to turn away a sick person because of lack of insurance, so they should be able to get things started at least. Hope this helps.
