for a long while i have had pain in my right kidney area. This past year i was unable to eat and i didnt have any desire to eat. more time than not the pain in my right kidney area. i am not drinker other than coffee, water at least any from 5 to 8 bottles on any given day, once in a while an occasional coke may be once a week for soda. any underline suggestions for doctors to check. I do FMD which deals with my arteries. my arteries in my neck were opened in my neck five years ago now which resulted in a stroke, this has created me to be put permanent disability. Sorry if my explaining is not understandable.
