My sister legs, feet, breast, hands have swollen up double the size, her skin is super tight and ashy. She says those body parts have a burning sensation and very,very sensitive to the touch- she went to the hospital, admitted and stayed there one week and the test results came back nothing is wrong, and discharged her and she is in the same shape. She will be following up with her primary physician in about week & half- earliest can get an appointment, but she is suffering miserably, any suggestions? Her concerned Sister
