Great.
I've been suffering from dumbness and tingling and cramping in my right leg including soreness in my right thigh, nighttime cramping of my right shin muscle and the top of my right foot. I finally went in for an "EMG" to test my nerve conduction through that right leg. At first I was unimpressed then the doctor started putting the electrodes on exactly the right spots, one after another. I told him, yes that's it... yes that's the next area... etc. He just kept going through the procedure. He finished and did tell me that he didn't find anything but "maybe you have a problem with your back." My back? That was a thought. I've also had stiffness in my lumbar and tightness that Advil or Aleve would take care of.
Talking around the office, I have a coworker whose wife is a chiropractor. I asked for a recommendation and was referred to a classmate of hers. This chiropractor has been a minor miracle for me. She first started out with an examination, a review of symptoms and an x-ray. The x-ray showed a spinal alignment that looked like a stack of half played jenga sticks. Precise measurements of which joint were off and by how much were shown. The alignment problem went from between my shoulder blades through to my hips. There are two bones that the spine rests on that were off by one and two millimeters. Small but clearly off.
She put me on a 3-3-2-2-1-1 week treatment schedule. Three sessions each the first two weeks and finishing after a total of six weeks. After several interruptions due to business travel I'm finally done. My posture is fantastic and the numbness and cramping are gone. I asked her why I was having problems in those areas I'd seen during the EMG and she opened up an anatomy book and showed me. It was similar to what is shown here,

All in all I was very, very reluctant to visit a chiropractor. I had heard the stories describing indefinite treatment schedules and a voodoo like approach to medicine. However I found that for my case, with my chiropractor, the results were excellent and my concerns invalid.
Of course I think it's a good idea to visit a doctor first.
