I helped this man out of his car after it flipped over and some of his blood got on my hand where there were no cuts, and on my sleeve. When i pulled off my shirt, its possible the sleeve could have brushed against the surface cuts under my nail and Im just concerned about possible transmission of HIV or Hep B ... the ER said it didnt stipulate receiving PEP, but should i go for a sevond opinion, or am i being irrational??
