I think I get this too. Thanks for tip of raising arms over head, that seems to work great! Problem is I can't stay like that for long lol. Mine is more of a feeling like someone is sitting on my upper abdomen. Like a lot of pressure. Occasionally it is accompanied by horrible back spasms in which case I just have to lay flat on the floor for awhile. Sitting definitely makes it 10 times worse. Maybe it's not a hug, not sure.
