Shower with a black widow spider

I found this black widow spider in the shower with me this morning. I carefully tried to carry it outside, wearing a towel,  on a wash cloth only to find it was not there. On my return to the bathroom, who was waiting for me on the wall. She does look nice on the green wall, but I'm not thrilled.
If bitten, here are a few things I can look forward to:
The danger of being bitten by a Black Widow is that the victim most likely will not feel it. However, there are some symptoms to look for, which may include but not be limited to: abdominal pains, sore muscles, especially on the feet, a dry mouth and paralyzed diaphragm, excessive sweating, and swollen eyelids. If a Black Widow spider bites somebody they should seek medical attention immediately. The victim is usually given antivenin or calcium gluconate.
Sounds like I'd better find her before she finds me.
