Step 1. The top row of colors allows you to select a color or related number that represents pain intensity. This is how severe or intense the pain is.
Move the mouse cursor over the button that represents your pain level and press the left mouse button. Now when you "draw" on the outline below you will use the right color.

Step 2. Now move your mouse cursor over the body outline. If you press the left mouse button while you move the mouse it will leave a colored line over the path you have just been.
This will allow you to outline an area to illustrate the location of your pain. You can vary this as much as you like.
Step 3. When you are happy with how your illustration looks, then you can click the "SEND" button to go the next page that will allow you to enter an email address to post this image.
