After waking up I go to the toilet. During first time the bowel movement is proper. But after some time again the pressure comes and I have to go to the toilet and stool comes out in small amount compared during the first time and sometimes no stool comes out but the pressure is released. After coming out of the toilet it feels like the stomach has expanded and also I feel some cramps in my muscles. There is also some pain around the anus area. Whether it is due to going to the toilet frequently or not, I am not sure. I am taking proper diet such as fruits, raw vegetables. Not eating outside food. Please tell me what is the problem and advice me some medicines. Should I have to go for some tests.
