One of my favorite websites. The WebMD Symptom Checker is designed to help you understand what your medical symptoms could mean, and provide you with the trusted information. This tool does not provide medical advice It is intended for informational purposes only. It is not a substitute for professional medical advice, diagnosis or treatment. Never ignore professional medical advice in seeking treatment because of something you have read on the WebMD Site. If you think you may have a medical emergency, immediately call your doctor or dial 911.
