(((Dej))) Giving you gentle hugs.

Could it be from MS, absolutely. It sounds like a milder form of the hug. This was one my presenting symptoms and one that I now deal with on a daily basis to varying degrees. I have it on my left side and when it becomes more "active" you can actually see not only the muscles in the ribcage but the complete outline of my stomach.

Ouch!
The good news is that your liver appears to be functioning normally. Phew!
I hope it is not a flare and that you start feeling better soon.
