What causes twitching sensation in the legs?

about four months ago I had a muscle twitch in my leg, about three days after returning from Afghanistan. The twitch lasted about three days and went away. Several days later I started getting random twitches in legs arms, feet, and less often my shoulder blades. I now how pins and needles in my hands and feet which has persisted for about three days. The symptoms seem to go away when I am active and return when I am at rest. Should I be concerned?

I understand your concern. Muscle twitching is also called fasciculations and are small muscle contractions in your body. Muscles are made up of fibers which are connected to nerves and stimulation or damage to nerves can lead to muscle fibers to twitch.
There is a long list of causes that can manifest with muscle twitching, the simplest of which being caffeine overdose or stress and long time being under hardship and duress. Post traumatic stress disorder can also manifest with fasciculations.
Besides stress, kidney related diseases, seizures, diseases related to nerve damage and low calcium levels can also cause muscle twitching. So I recommend you get a thorough check up, followed by the necessary tests and examinations in order to determine the underlying cause and get the proper treatment.

Wishing you good health and all the best.
