A woman goes into the doctors office and says "Dr. I have a problem, I fart all the time but my farts are noiseless and they don't smell...In fact, I have farted no less than twelve times since I arrived here!"
The doctor wrote down a prescription and said, "Take these for a week and then come back to see me."
A week later the woman goes back and storming into the office complains, "Doctor, I think the pills made it worse, I keep farting all the time and even though the farts are still noiseless the now smell terrible!, what have you got to say for yourself?"
Doctor: " Good, we have taken care of your sinuses, now we can move on to your hearing..."
