Just like many others, you have probably experienced going to the doctor and hearing him say a bunch of unfamiliar terms while you sit and pretend to understand. Face it, no matter how much your doctor tries to simplify things, they could still sound like a different language most of the time. As a result you just take whatever the doctor recommends without completely understanding how it will help you.
Knowing the details of your pains, however, is extremely important, because it allows you to consider various types of treatments and opt for those which you believe are best for you. This allows you to become a more active participant in your own wellbeing.
