Hard to say: Hi Scott, Sorry to hear you are feeling poorly. I know you are probably very worried, but it is good that you have an appointment to be seen by a doctor. Without more information and testing, it is very difficult to determine exactly the cause of your current symptoms. Preparing a detailed list of your symptoms, like timing, duration, severity, triggers, etc, can help your visit go more smoothly.
