You’ve got it!
Same thing happened to my wife in the last month. Turned out she was severely constipated. They also did many tests and found she has erosion in her stomach and is now on a bland diet for the next few months.
Here’s to hoping your wife will be fine. It truly does hurt when your partner in life in hurting.
By the way, sounds like something I had. . .it matches exactly how MRSA attacked my system. Same pains, same locations, same organs. . .
Again, prayers.
