Because so many symptoms that are realized during an anxiety attack are similar if not exactly like those of some other kind of condition, it is almost impossible to determine if what you have been feeling is due to an anxiety attack, or another condition. This is why it’s important to see a doctor and explain your symptoms, so that your physician can run the necessary tests in determining whether you have an underlying medical condition.
