I have been under a lot of stress this week and have had trouble with anxiety in the past.  I am not sure if I am having an anxiety attack or if it is something different.  My chest is tight and I cant take a deep breath,  my upper left arm is feel numb and there is tingling down my forearm.  I also feel very dizzy.
Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of stress and anxiety related symptoms is more. But better to first get done ECG and 2d echo to rule out heart diseases because they present with similar symptoms. So first get done ECG and 2d echo. If both are normal than no need to worry about heart diseases. Stress and anxiety are the causes for your symptoms. So better to consult psychiatrist and get done counseling sessions, try to identify stressor in your life and start working on its solution. You may need anxiolytic Chat Doctor.  So don't worry, you will be alright. Avoid stress and tension, be relaxed and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
