Periodically, i get muscle twitches in both my hands and it's starting to feel like in my feet. it's annoying but painless. should i be concerned?

Overuse vs Disease: When muscles are tired they might twitch, but it is unusual for this to occur regularly. Unusual unless you do something quite repeatedly to the point of exhaustion. If this is not the case, you should consider seeing a neurologist. There are some benign muscle conditions where muscles twitch, like Benign Fasciculation Syndrome and there are management strategies, so a physician can help.
