i have intentionally checked myself before bed. no hug. I lay down, start to watch TV and 5 mins later, im hugged! once it starts its hard to make it stop. I get up. I sit bolt upright for it to go away, which takes a 1/2 hour or longer. Back to bed. Lay on other side. and sometimes I get hugged, sometimes not. laying on my back or right side is a good bet it will come. laying on my left side puts me face to face with fuzzy Jack and when I snore he puts his dirty fuzzy foot in my mouth. ICK! I find when I lay on my back its worst under my right rib cage. One MD told me I was crazy! that isnt how the hug works. I would have other sx in my legs and torso first. ugh! then another MD told me that is exactly how it works. putting pressure on the area with the lesion can make it fire up. I wish they would all work from the same book.
