Do you know something we don't that makes you more insistent? It's reasonable to assume that between the low cost of sanitary products, the availability of fresh needles and the simplicity of known best practices, an infection or abscess is highly unlikely. Also, an abscess is generally localized. It can grow to an obscene size but it doesn't 'spread', it grows from the point of origin, creating a disproportionate protrusion from the center to the edge of the abscess wall. It wouldn't form an even blanket of tissue because then, like a bacterial infection, it would have become systemic and manifested throughout the body. Do his abs look swollen? His face?
