Can Household Electric Shock cause tissue damage?

I got a shock from 110v years ago - I wasn't exposed for very long and I had no skin burns but I have been convinced that somehow the current had damaged tissue or nerve endings in my penis. Obviously it wasn't connected to ground but I could feel the charge exit partially through the tip. Could the shock have permanently impaired tissue internally? When tissue resisitence is high you get surface burns but when it is low as in this case you may have internal burns. Doctors have all said lasting damage just wouldn't have been possible but I still wonder if I'm the exception to the rule. I have had problems with (lack of) sensation that I date to that event. thanks for the input.

this is personal advice, not medical advice

the problems are probably psychosomatic. however, it is POSSIBLE for a nervous system to receive damage from a powerful electric shock. very powerful electric shocks, such as lightning, can cause very unusual problems that last a lifetime. however, lightning is MANY orders of magnitude above 120 VAC.

your particular situation sounds to be unlikely on the face of it. there is a slight chance that synapses or parts of the cell body were damaged, but based on what you wrote, i would be most likely to call it a psychosomatic response

your best bet is to discuss this with a neurosurgeon, since most other physicians may not have the extremely specialized information to make a good diagnoses.
