Well the urologist confirmed that it's "only" a hydrocele. As long as it's not causing any pain or isn't too uncomfortable then my best course of action is to do nothing and it will more than likely go away on its own. 'Course if it gets worse then surgery may be needed, but I choose not to dwell on that right now.
I have a feeling that the cardiologist appointment tomorrow won't go quite as smoothly. A blood pressure reading of 191/101 is usually a sign that something is amiss.
