You should see a doctor if you answer yes to any of the following. Do you:

Have repetitive thoughts that are not simply about real-life problems?

Do the same activity repeatedly and in a precise way each time, from constantly washing your hands to checking that doors and windows are locked and appliances are turned off?

Do you soon feel the need to repeat them?

Do these thoughts or actions take up more than one hour a day and/or interfere with your normal routine?
