Sounds to me like you were noticing a blood vessel that usually you don't see. The heat of the shower likely caused it to dilate to the point you noticed it. You might try sometime putting a heating pad on the area and see if you can reproduce the "line". If so, it's a pretty shut and dried case that it's a blood vessel. Nothing to worry about!
