Hi, I have a small (not very deep) scratch on my arm that I didn't notice right away. It swelled a little and at first I thought it was a knotted muscle (before I noticed the scratch). It also has caused some tingling in my arm. As soon as I noticed it I washed it thoroughly and applied neosporin. It seems to be getting better. I'm not sure what it's from but I have recently been moving and cleaned out a storage unit with some mice in it, I'm a bit worried it's from a mouse I didn't notice get on me, but it could well be from something else. Should I be worried?
