One common problems is laxative overuse. Overusing laxatives to relieve constipation can actually worsen constipation. Also, medications can cause constipation, including Mylanta or other medications. Stress or a busy schedule can cause constipation, including being extremely worried about your constipation. (ironic)
However, constipation can also be a sign of more serious conditions. Instead of your primary physician, maybe you could get in to see a gastrointestinal doctor who specializes in conditions of the digestive system and who could do more detailed tests.
Also be aware of other symptoms. Where your stomach hurts, blood in your stools or vomit, changes in skin or stool color, fever, and things like that.
