Do you possibly have fibromyalgia without having been diagnosed yet? A classic characteristic of fibromyalgia is that a relatively light pressure on the tender points feels more painful than pressure on other points of the body. (Healthy people can also have painful tender points, but they are usually far fewer and less painful.) At least 11 of 18 tender points should be very sharply painful at pressures below 4 kg. You can press yourself so that the finger you press with presses just so hard that its nail turns white. All that happens is that you feel a sharp pain at that point much worse than if you press elsewhere. Sometimes you can also feel slight pain radiating from the point when you press it. For example, points at the top of the back can radiate up to the neck or out into the arm. But remember that it is not always the case that there are as many as 11 positive points in a patient. The doctor can then make the diagnosis based on the rest of the medical history. Good luck with the test.
