1.Pain in multiple trigger points
Pain is perhaps the most salient symptom of fibromyalgia. Several changes in the central nervous system and increased sensitivity in the peripheral nerves increase the sensation of pain in different parts of the body. Pain symptoms are not limited to headaches or pain in the articulations. Instead of being localized, this pain becomes widespread and often difficult to localize. When other diseases are also present, it might be difficult to differentiate which symptoms are triggered by fibromyalgia and which ones are caused by the overlapping illness.
In fibromyalgia, there are several trigger points throughout the body that are usually painful. Some of them are close to bony structures and organs that become tender to the touch. Doctors use these trigger points to diagnose fibromyalgia and may need to apply a bit of pressure in each to see where it hurts.
In fibromyalgia, pain nerve terminals are activated in response to inflammation or may become triggered spontaneously. Your hormones, stress, and specific emotions may contribute to the problem.
