I Was Lifting Weights Wednesday And I Pinched Myself With

I was lifting weights Wednesday and I pinched myself with the weight bar causing it to bleed. I told my Coach about it and she told me it was fine. I continued to lift weights and the weight bar was rusty. I knew that would infect the cut, so after the class I washed my hands. Thursday, it was itching and swollen. I went on to school and when I got home it got itchier than before and more swollen. When I touched it not only did it hurt, it was very warm.
