You honestly need a medical professional's opinion. I believe they cause rapid and shallow breathing, chest pains and sweating. Somewhat similar to how a heart attack feels. If you feel you may have anxiety or any panic disorder/attacks consult a doctor or a psychiatrist, they can provide medicine. A psychologist would be able to help with therapy and help you cope with any issues.
I would encourage you to see a doctor, to help you determine what is really going on. Many illnesses, such as heart conditions, diabetes, low blood sugar and thyroid dysfunction, can cause what appears to be anxiety attacks. You may want to see a doctor, to find out for sure. Take care.
