Felt like paralyzed for a while like I could not get the muscles to move to get me up. I could speak but I could not get up. Probably after a few minutes I could get up and then after that I was able to get myself to the sofa and if I was trying to walk my body would be like it would tremor like severe tremor and that eased out after several minutes then (incomplete sentence).
