I work with mentally handicapped people. One particular resident has been consistently sick. His hands and fingernails are always germ infested. He has an aggressive side, trying to hit, punch, kick, scratch etc. He got me last week, dug his nails deep into my arm and twists. I cleaned it up well. But this week, my arm has been stiff and sore, and at times very painful. My calve has been getting muscle spasms when walking, and I ve been very week and light headed. I m off work now. I actually just thought of this incident tonight, is it possibly a blood infection?
