A drain leak, a leaking shower pan, a leaking shower valve or piping, a leaking bezel or escutchions on the shower valve, bad or missing grout, bad caulking in the corners of the wall, a leaking shower door, water spilled on the floor, or, a drain pipe leak. any one or combination of the listed problems can do it. Look things over take care of what you can see wrong before making a hole in the ceiling. If you think you have fixed the leak repaint the stained area but prime 1st with Kilz or Binz to cover the stain or it will reappear through the paint even if the leak has stopped. If the leak hasn't stopped from taking care of the things you could see then open up a hole to see where it is coming from.

You think that your ceiling fan is giving you a headache in the morning?

Mine? No. Yours? It's possible. If you lie in such a way that the breeze from the fan dries out your sinuses during the night it could. If your ceiling fan is noisy and running all night it could cause a headache. If there are poorly sheilded eletrical wiring in your ceiling fan and you are sensitive to electro magnetic fields that could cause a headache. If your ceiling fan is hung too low and you bang your head on it in the morning then that would probably cause a good headache. If the ceiling fan falls from the ceiling onto your head that will almost certainly cause a headache and/or concussion or serious injury or death.
