What Causes Feet, Legs And Eye Twitching, Body Weakness, Dizziness And Syncope?

Hello, for the past week I have had a variety of odd and new symptoms to my body. Last week I started experiencing twitches in my right foot and my right eye. It later progressed the next day to both feet and legs but same eye. These symptoms have been off and on, sometimes intense and persistent or nonexistent at some times. I have no trouble when going to sleep but notice symptoms mostly when relaxed sitting down. Symptoms don t show up when moving around. I also have had a very general feeling of weakness throughout my entire body, I have also begun to shake throughout my body. Yesterday I began to feel very dizzy and felt like I could faint. Again these symptoms come and go but they have made me very stressed out. I have doctors appointment tomorrow but am wondering if it is something that is more urgent? Thanks.
