I am anemic have had iron infusions, weigh 257, 5 4 tall have undergone upper and lower GI all is ok, had cat scan several times, MRI,two on my back one with contrast as dr had saw something he needed to look at it was hematomas on my vertebrae the reason for this testing was going to have shot in my back for pain did not help maybe a little worse, have had stress test neculair , had a knee replacement two years ago, and need the other one done bone on bone but must lose some weight first, have restless legs also. I have been falling one week 3 times. Then won t fall for some time then fell the other day. They can not find where I am bleeding but continue to be anemic, I know this is a lot of questions but need to know where to go from here. My family has Marfan syndrome but the say I have no signs of this. Help
