Dear Doctor, This is the first time in life I am having constipation. Yesterday this problem started and took a laxative tablet (Canthalax) and one now. From day before yesterday I did not go for motion and the laxatives did not help. I do have the urge to go motion but i feel the stool is as hard as stone and it isn t coming out. My stomach is paining. I have the urge to go motion. Please help me out.
