I bicycle quite a bit, and recently had a crash where I have some fairly extensive road rash on my hip, knee, calf and shoulder area. While most are fairly scabbed over, the ones on my shoulder and knee tend to crack and bleed with movement.
What are the precautions I need to take when going to work and/or the gym? I want to protect myself against infection, but I also don't want to leave a gory trail behind me either.
