Toe/foot twitching 5 years non stop

Hi all. I have had constant toe twitching in my four small toes for the last 5 years. It has been non stop since it started, some times less twitching but some times it gets really irritated. At other times I can also see my arch and heel twitch/pulsate. I’ve had an EMG and it was normal. I am concerned something is being missed and I have compression from a tumor or something along those lines. Any insight would be much appreciated.
