hi there prairie dog and welcome to the board.i have really bad arthritis and have for many years.back in early 90's the doc gave me somekind of med for arthritis,(i can't remember the darn name of it)anyhow i took this med and after a couple of weeks my stomach started bothering me so i went back to the doc.he had some tests etc. run on me and here i had developed a hyetis(not sure of spelling)hurnea!he took me off the meds.so i feel that whatever was in the meds that he gave me ,could have caused the hurnea.hope this helps
keep the faith,bless you
