Summarize this article in one sentence.
The pain scale is used by doctors to help determine the severity of your pain. The pain scale is numbered from 0 to 10, with 0 being no pain and 10 being the most severe pain. You can rank your pain on the scale by choosing a number on the scale. The scale is as follows:  0 - No pain, feeling perfectly normal. 1 - Very mild pain. 2 - Discomforting pain that is minor. 3 - Tolerable pain that is noticeable but not overwhelming. 4 - Distressing, strong pain that you cannot adapt to. 5 - Very distressing, strong pain that gets in the way of your normal lifestyle and routine. 6 - Intense, strong pain that affects your senses and clouds your thinking. 7 - Very intense pain that dominates your senses and is debilitating. 8 - Utterly horrible pain that overrides your senses, your thinking, and your personality. 9 - Excruciating unbearable pain that require painkillers or surgery. 10 - Unimaginable, unspeakable pain that is the worst pain you have ever experienced. Based on the pain scale, your pain is considered minor if you fall within 1-3. Your pain is moderate if you fall within 4-6, and your pain is severe if you fall within 7-10.  Your doctor may find it useful if you describe your pain as minor, moderate, or severe using the pain scale, as they can then more easily classify your pain as a symptom. Keep in mind that people have different levels of pain tolerance, so your idea of minor pain may be someone else’s idea of moderate pain. Your doctor will take your pain tolerance into account. In most cases, the pain scale comes illustrated with cartoon faces that move from 0 to 10. The illustrated face at 0 is smiling and pain free, while the face at 10 is weeping in agony. You may be able to describe your pain best to your doctor by pointing at a certain face on the scale. The illustrated faces on the scale are often most useful for people who respond visually to pain. This can also be very helpful in a crisis situation where someone is unable to talk, or in small children who have difficulty describing their pain. The pain scale is widely used by doctors, but it is also not the only way for you to describe pain. Sometimes, it can be hard to place your pain on an exact number on the scale or within a certain range. Your “5” on the scale could be someone else’s “7.” Your doctor should keep the subjective tolerance of the pain scale in mind when they are using it to diagnose and treat your issue.

Summary:
Look at the pain scale. Identify if your pain is minor, moderate, or severe. Chose an illustrated face on the scale. Keep in mind the subjective nature of the pain scale.
