If you are only affected in the legs, then metabolic or drug issues are less likely. However the large muscles often appear first when something goes haywire.
I think Peter's suggestion is good. Sometimes just a little magnesium supplement does wonders.
You can also soak in the bathtub with about 4 oz of epsom salts to a tub of WARM water...if you see relief, that is a clue to getting some magnesium in supplement form or eating more magnesium source foods.
Here is my thread on it:

I think anyone with chronic muscle pain, should have a CPK test run. This will show if mitochondrial issues are a potential cause.
This is fairly underdiagnosed it is thought today.
Muscle pain can also come when blood sugar is off. During low blood sugar episodes, you may have aching/burning or twitching in the muscles.
