HELP! I Am Electrically Charged And I Don't Know Why Or How

OK. This is the 2nd time this has happened, and I'm really trying to seek out some answers.

I went into the bathroom to get a shower. I undressed, flip on the exhaust fan, and then turned on the hot water. When I put my righthand under the hot water to make sure that it was hot I felt a tingle in my arm. I then grabbed the handle to turn off the water (as I knew this meant I was electrically charged because I went through this about 2 weeks ago). I could feel an electric tingle going through my arm when I grabbed the handle and turned the water off.

Suspcious that it might have something to do with the exhaust fan (although no one else in the house is having these problems) I turned off the exhaust fan and tried turning on the water again. Again, when I touched the handle I got the electric tingle through my forearm. It feels sort of like the electric tingle you get from putting a 9v battery on your tongue.

Now, let me tell you the story from two weeks ago.

I went through the same routine as above, but that time I went and got my wife. I had her touch the handles and the faucet and she felt nothing. Then she grabbed my arm and touched them and she felt the electricity going through her and into my arm (or vica versa). She then tried it out at the kitchen sink, but NOTHING. It only occurs in the bathroom, and only in conjunction with the bathtub.

I originally thought that maybe I got an electric charge because I went from a cold house to a warm outside and then came back in and went to get a shower (electrostatic charge), but this current time I was outside mostly all day, and in and out.


I should also mention, that the caulking on the tub had cracked before either of these experiences and I did not realize it. Some water damage got done before I knew about it, but I have since fixed that. I don't know if that could be part of the problem, especially since no one else is experiencing this.

I've never had any kind of electrostatic charge where there is no spark when you touch metal, before. This is a totally new kind of experience for me, and its really freaking me out. I am afraid to take a shower when this happens.

Is there anyone out there who has a suggestion as to what is causing this problem and/or if there is some sort of name for what I am experiencing? As I said earlier, it is not in my head, my wife felt it too.
