I called my sister in France yesterday and we concluded we have the same symtpoms: irregular alternance of D and C, painful abdominal cramps, all triggered at first several years ago by tropical infection. (in my case, amoebia in India, in her case I don't know, something from an African Island)
She told me endoscopy showed nothing and no treatment helped her and Probiotics makes her worse
Ultra-levure (or ultra-yeast, Saccharomyces boulardii) helps a lot
and ****su brings good relief.
I like these news because both are natural remedies.
She'll call me on Sunday to discuss further
