In this section you can find information on the symptom you are experiencing, for example abdominal pain, headache, breathlessness and leg cramps. Our doctor-authored leaflets explain the symptom, the kind of people who might experience it, what investigations are commonly done to make a diagnosis and which conditions may be responsible for causing that symptom. You can then follow the links provided to read more about specific possible causes of your symptom. There is also information about what you should do when you have that symptom - for example "Should I call an ambulance if I have severe shortness of breath?". If you just need a bit more confidence to manage a symptom at home, for example "How do I treat my cough?" then our information will help you.
