Since I have the ms hug, I also would have automatically ruled out the gallbladder, until I had to have it removed last week. My neuro didn't want to just blame all the pain on the hug. So when they did an ultrasound they found some gall stones. So, now I am a believer in not just taking for granite it is JUST ms.

I wish you the best.
BTW: I have been told here that the hug is caused from a spinal lesion.
