Maybe you are a synesthete
Well it is odd what synesthesia can do. I have it, but I've never heard of this.
Referred pain perhaps?
It could fall under either of these two cases of Synesthesia:
Auditory-tactile synesthesia may originate from birth or acquired sometime in life. It is one of the rarest forms of synesthesia. In a 2008 article, Beauchamp and Ro reported on a patient with a rare infarct restricted to the ventrolateral nucleus of her right thalamus. This infarct had initially resulted in a loss of somatosensory sensation on the contralateral half of the patient's body. Although this deficit completely disappeared within a period of 18 months, the patient developed symptoms of auditory–tactile synesthesia, where certain sounds induced intense and often unpleasant somatosensory tingling sensations in her left hand and arm.
Mirror Touch Synesthesia
In this rare form of synesthesia, when you see someone else being touched, you feel a touch as well. This means that you can literally feel the pain of others when you see them get hurt. People with mirror-touch synesthesia, often score high on empathy tests compared to people without the condition.http://en.wikipedia.org/wiki/Synesthesia
Maybe he has a very rare form of self-mirror touch synesthesia where he experiences phantom pain or feels sensations on one body part when he touches another body part, almost like Dr. Ramahandran's famous phantom limb syndrome.
I think we need to do a full autopsy on him to see if we're correct, tho. It's for science, so it should be okay.
