I am waiting to see a Rheumatologist to see if I have Reactive/Rheumatoid arthritis or Fibromyalgia. I have many of the overlapping symptoms from all 3 conditions, but one symptom I have which I cannot find an explanation for is my legs refusing to move. When overtired last week, my legs just stopped working, they didn't go numb as such as I knew they were there, they didn't go weak as I was stood at the time - they just failed to work. I was screaming at them in my head to move but they just wouldn't - this happened 4/5 times for 2/3 minutes each time. After sleep they were fine, but now when I get over tired my legs and hips start jerking about all over the place. I have had restless legs at night for about 4 years - but this is a whole new level - while awake! Has anybody else experienced this lack of leg movement and change between not moving/jerking when tired?
