My daughter has many health problems including repaired ToF, repaired imperforate anus, urinary reflux, agenesis of corpus callosum, and repaired bilateral cleft lip and palate and multiple vertabrae fusions they are worried about problems developing in the future. She loses weight a lot she is almost 3 and 20lbs, she has what seems to be enlarged inguinal lymph nodes, and she gets dark bruises along her spine for no reason. I just want to know what are possible causes for the lymph nodes and bruising... should i be worried or am i just being paranoid from past history??
