Fibromyalgia is a neurological disease where your nervous system does not accurately manage signals to and from the rest of your body. This is why the symptoms for fibromyalgia vary greatly. For example, you may feel stinging pain by someone playfully nudging your arm. You think to yourself, based on your entire lived experience, you know that it shouldn’t hurt because they didn’t hit you hard but it did really hurt you. You may also have itching that is not caused by anything that you can figure out like a bug bite. When you walk into an air-conditioned room after being outside in the heat, it may take you a very long time to cool down. You may have random stabbing pain that comes on quickly and stops just as fast. You may also have very sore nagging pain. You may also experience more ringing in your ears, and increased intolerance to loud noises. All of this is based on how your nervous system is handling signals from the nerves traveling through your body.
