2 months ago I had about 3 weeks of liquid stools with few solid elements. also a change in color which is now sometimes dark brown and a little black. also in last 3 months have developed edema in feet and upper legs. no pain in abdomen or colon ... I also have secondary addison's due to empty ella turcica which caused a failed pituitary gland resulting in secondary addison's and failed thyroid I have an end. dr. and am going to become a pt. at emory in atlanta. I also only have one adrenal gland. A lot to lay on you, but if you have any additional advice esp. about the swelling. I am a nurse so nothing will alarm me to much. great service, thanks
