Can stress cause a lot of body symptoms?quit job and feel very ill bodyaching headache dizzy chestpain can it be fibromyalgia?im always worried

Sure: Emotional or physical stress can cause any or all such symptoms. That's why it is good news when such symptoms go away with the resolution of a patient's emotional or physical stress... it would suggest a high likelihood that such symptoms were due to stress. The opposite is also true. Such symptoms might not be due to stress, if removing all the stress does not lead to resolution of the symptoms.
