I woke up in the middle of the night last night with abdominal pain. When I got out of bed I noticed I felt very weak and strange. I went to the restroom and as I sat there I began to sweat excessively to the point where my pajamas and body were completely soaked as though I had just got out of the shower. I began to feel weaker and shouted for my husband. when he came in I was on the floor and my body felt tight . My hands got stiff and in a strange position with my thumbs turned inward. I had no abilty to straighten them. although it felt like an eternity I think it lasted only a few minutes. Today I feel completely drained, tired and unproductive. I had the exact same situation about 2yrs ago....only difference is that I also had stiffness and uncontrolled movement in my face as well. I have not been ill with a cold or flu for a very long time.
