Homeopathic medicine. Constipation for long time - 10 to 15 years. Very offensive odour gases. When I take any laxative then I have to go 2-3 times for bathroom, and still I don't get full emptiness feeling. Any weather change, change in food, change in city, etc causes constipation and offensive odour gases due to which I can not mix-up in people freely. I have used carbo veg 200, nux voice 200, pulsatilla 200, alumina30, etc but no effect. My age is 37, I am very shy and quiet in nature. Physically very weak, angry but I don't express my anger and other emotions, nervous and sad in nature due to some previous bad life experiences. I always feel low in energy. Please suggest any good homeopathic medicine.
