Some people have a fear of being in crowds, standing in line, or going into shopping malls. They are afraid of having another panic attack or of not being able to escape. This problem is called agoraphobia. It can be so bad for some people that they never leave their homes.
People who have panic disorder often have depression at the same time.
Your doctor will ask about your past health and do a physical exam. The exam may include listening to your heart, checking your blood pressure, and ordering blood tests to look for other causes of your problem.
Treatment for panic attacks and panic disorder includes counseling, especially cognitive-behavioral therapy (CBT). Medicines may also help. Treatment can help most people control or even stop attacks. But symptoms can come back, especially if you stop treatment too soon.
