Thank for asking to HCM
I really appreciate your concern you became too much conscious taking the health issue of your wife in fact the "Fibromyalgia" it self is psychological condition, and such condition always associated with other functional element and that responsible for many nonspecific complain that your wife might be having, in my opinion such case need to be treated with the following drugs on trial basis,
1) Tab Omeprazole
40 mg once in day
2) Tab Chlorodiazepoxide three times I day
this is not the chron's disease, and no need to worry about this, hope this information helps you , have a nice day.
