Yes. My friend had an infection in his hand from an iv. He also used needles himself. His had between his knuckles n wrist swelled up huge. It s been like this for months n he can hardly move his are.. he has been to the doctor multiple times. At one point they told Jim he had a staph infection. I don t think they r even treating Jim any more. He was treated with septic embuli in his lungs when this first started.
