I have hereditary multiple osteochondromas. My granddaughter has been having swelling of her joints with pain in her hands. I am suspicious that this may be a manifestation of my disease. I had always been under the impression that my children did not have this disease. My father was the one who passed the disease on to my sister and I. I would like to find someone that would like to help me follow up on this and to find out if this could be present in my daughter or grandchildren.
