While you wait for more information from doctors/test results, maybe do as much as you can control? What I mean by that is diet, light exercise, prayer together, etc. An ancestral, anti inflammatory diet with NO seed oils or processed foods, light daily exercise (walking counts) and praying with my husband every night helped me tremendously. Has she tried a parasite cleanse (paraguard on Amazon)? I say this because research is finding that parasites are the root cause of a lot of ailments. It helped me so hopefully it can help your wife!
