Jack, I don't know if this is the same but I often feel a pull on my body to the right that causes me to lean to the right most of the time. At times--which are coming with increased frequency lately--it-it feels like a very strong force that has made me fall, fall out of chairs, and makes it impossible for me to get up without help. One time, my sister had to call 911 to get me out of the bathtub. I started having these feelings after my back surgery about 2 years ago and, as I stated above, they have been occurring more often recently. I cannot figure out what causes them or any pattern to their occurrence. If you or anybody else has some answers, PLEASE share them with me. And, good luck with your friend. Marty Polonsky
