He also reports pain behind the left ear and decreased lacrimation from the left eye. He has been in good health and had his yearly physical examination 1 week ago, which was normal. His lipid levels, chemistry profile, and CBC were all normal. He has not been involved in any outdoor activities, nor does he engage in any high-risk sexual behavior. On examination, there is flattening of the left nasolabial fold and decreased ability to close the left eye. The mouth appears to be drawn to the right. The remainder of his general examination and neurologic examination are normal.
