So my niece whom I have posted about before on this site has finally gotten a diagnosis. She has been bedridden for about 6 months and they couldn't find out what was causing the pain and illness. She has gone from a size 14 to a size 8 because she can't keep anything down and is in constant pain. They had her at Sick Kids Hospital in toronto for almost 2 weeks and never found anything. They finally did a muscle biopsy and 6 weeks later they told her she has dermatomyositis. Does anyone know anything about this disease? I think she told me the doctors said it was an autoimmune disease of some kind. She is being treated with a large dose of prednisone and it has really helped. Could this have any relation to the high blood sugar readings she had before she was diagnosed? They still say she is not diabetic.
