My thigh muscle twitch when resting. I work out and the twitching is above my arthritic knee. What causes this? It only twitches during rest.

In brief: Muscle twitching

Muscle twitching occurs when individual fibers of the muscle spontaneously contract.
This is common after changes in exercise regimen, changes in blood chemistry, and changes in nerve supply. It is very common when implementing newer exercises or with irregular exercise frequencies. It is also common with changing the resistance in work outs.

In brief: Electrolytes

You probably have an electrolyte imbalance.
Try taking a magnesium/potassium supplement (unless you have kidney problems - then discuss with your doctor).
