“My husband had similar issues, turns out he had undiagnosed coeliac disease. I suggest its worth one more blood test to check, when he started to eat gluten free, pain went with it.
Heunfortunately also got non hodgkins t-cell lymphoma from not having it diagnosed early enough, and had to have chemo and everything for duodenum cancer so its well worth ruling out. He had no symptoms of being coeliac, none at all, and is 61.”
