Anxiety is an uncomfortable feeling of fear, uneasiness, or concern that something bad may happen. Anxiety can cause physical symptoms such as trembling, shaking, muscle aches, restlessness, insomnia, rapid heartbeat, sweating, and clammy hands.
If anxiety interferes with your daily activities, you may need treatment with medicines (such as antidepressants or antianxiety medicines) and/or professional counseling.
