A diabetic patient complained of feeling a tingling in his feet and hands, which to his physician sounded like the beginnings of diabetic nerve damage. Paradoxically, though, he only got this sensation in the shower when adjusting the showerhead. The man was accompanied to the physician鈥檚 office by his wife who overheard his comments about the shower. She immediately volunteered the information that she had experienced the same tingling when she touched the showerhead. An electrician was called and found the electrical system was not grounded properly and that electricity flowed through a body that was in contact with the metal showerhead and the bathtub at the same time. An electrifying, but not a diabetic experience.
