Yesterday I had a new "issue". My legs felt really weak. My right leg actually began to quiver as if I had just done 3 sets of leg presses. I felt like they were going to give out on me. My right leg is better today but still they are very weak. When I drive, if my foot is pushing down on the accelerator, it begins to quiver and shake uncontrollably and I have a hard time controlling my speed! If I am at a stop light, I have to use the e brake or alternate feet so that my right leg does not get fatigued holding it down. I have an appointment with a new doc in 2 weeks. I am a bit concerned that I am going to fall or get into an accident. Any clues what is going on or what I can do?
