Get help figuring them out by answering a series of questions. To get started, click on male or female, regardless of age, then the part of the body that is troubling you. Use the Symptom Checker to select parts of the body where you are experiencing symptoms." Why pay a doctor to misdiagnose you, when you can do it yourself? <http://symptoms.webmd.com/symptomchecker>
