I recommend you to take care of yourself by natural and organic methods. Before going to a doctor, you must take some precautionary measures to get rid of constipation. Actually, I also had the same experience and at that particular time, I was abroad with my mother (in Pakistan) and discuss my situation with her. At last, she search for the "qabz ka ilaj by remedy pot" online, and then she suggest me few tips such as drinking more water, taking veggies, staying away from beef and fried food, going through regular exercise, and taking plenty of fiber.
I consider all these tips and finally, it works.
