What could be some possible causes for eye twitching? First my left eye was twitching and now my right eye is twitching. It happens every 5 minutes and lasts about 30-50 seconds each time. This has been going on for over two weeks. I've had twitching before but lately it's become a regular thing: I get the twitches, it goes away and then comes back. Any suggestions as to what I should do? TIA.
