Of course eye twitching can be caused by stress. If you are suffering from great stress at this time, I suggest you to relax yourself immediately. If you have suffered from stress for a long time, you may get other health problems. I heard that drink a lot of water and do some exercise can help reduce your stress. Or you can hang around with your girlfriends on the streets and buy something to please yourself. I think shopping is a good way to help reduce stress and anxiety. How about stop all the works at hand and sleep for two days at home? Ha-ha! I know this sounds a little ridiculous but I just do this when I feel the great stress because I know that I can do nothing well with great stress and there will be a lot of mistakes, so I choose to relax myself first and then go on with my work and study. Hope this helped!
