I am very new to this and haven't yet been diagnosed as having FM but for a couple of months now, I have been having some really weird symptoms. Dizziness, panic attacks, chronic diarrhea, chest tightness, heartburn, and aches galore! For the past two mornings, I have woke up with my arms aching like they would bust. Just like flu pains. My fingers also feel stiff. A few weeks ago, I woke up and my arms were as sore as if I had lifted weights the night before. This is all very frightening for me and I would like to hear from others who might share the same experiences.
