RLS is real. (puts on professor's hat)
The body works because of a few things. Chemical reactions, electricity, physical structure, and plumbing.
Physical structure is easy to find problems in, usually. Take a picture. X-ray, MRI, something like that.
Plumbing can be checked in a number of different ways, doppler, ultrasounds, MRI's even.
Chemical reactions can usually be measured in the bloodstream, other lab tests, or simple observation.
Electricity in the body, however, can be tricky. With the current technology, about all they can do is tell if a nerve can conduct electricity, or if electricity is being produced, like in an EKG. They can't tell if a nerve registers heat, cold, pain, ticklishness, whatever. Just on or off. Here's where RLS comes in. It can have different symptoms in different people. Sometimes radically different symptoms. In some cases, it can mask another problem or be the result of a different disease altogether. Some in the medical profession think it may be a family of syndromes, similar in nature, but distinctly different, which is why some meds work for some patients, and not for others.

Gross oversimplification there, but you get the idea. Which is why you can ask 5 different doctors about something kinda obscure, and you may get 5 different answers.
