Hi. I Am A 49 Yr Old Woman, Who Has

hi. I am a 49 yr old woman, who has ovver the past 8 months lost 70 lbs. My Dr. has ran every blood test for sto sche, bowel. My throat feels like there is something caught in it at times. My body is sooo weak. Shaking, profusely sweating, chills all the time and tingling in my hands. Just now I was reading on thyroid issues. Does it sound like thyroid issues? Had pituitary tumor when I was in my early 30's. Went away on it's own. Can't work. Feel helpless, getting depressed. Help!suzq905@gmail
