Felt like I was coming down with something

I felt like I was coming down with something today.  I took my temperature several times, but it was normal.  I went out to the park this evening to meet up with the group, with the intention of running one mile.  I kept going and ended up with two on the park roads, without the sling.  I'm still required to wear it through the end of this month, but the doctor said that it was okay to run without it, as long as I kept my my arm down.
