I was suffering from panic attacks quite frequently, but they vanished off to maximum. My head is feeling quite good now, there is less effect of anxiety now. However I feel frightened in going out for a walk thinking that it may lead to my palpations to raise. I feel quite stinging irrigation exactly at left centre of chest and to its opposite of back side. Kindly tell me should I go for cardiology checkup as I had done same a year ago with every ECG and digital X ray found normal. Last x-ray I did in June and ECG too. Recently I consulted a physician who advised me to take lamplus and estivin medicine as course. My question is should I really be concerned about this stinging issue. moreover I feel quite energy less these days.
