Whenever I go outside my house especially for attending my college classes, coaching classes, to visit any temple, to attend any party-function or to do any journey by bus, car or train I have to go for passing stool immediately and a number of times. This situation becomes worst whenever I have to appear for any examination or interview or to attend any meeting with any person who is sitting in a very high post in any job such as a doctor, police inspector, bank manager etc. This time the frequency to go for passing stool increases very fast. Also this time I get breathlessness and suffer from heart palpitations. I get trembled and my words get stuck in my mouth only and become unable to speak fluently . Excess sweating comes in both palms and foot soles. It becomes worst whenever I feel that I will get any bad news within a few moments. This time also I become breathlessness and suffer from heart palpitations and finally I have to go for passing stool immediately. Effective medicine?
