Hello. We have a 4 year old girl who is having multiple symptoms. When putting all symptoms together, I realized there is something really wrong. She has very blue and bulging veins, constant tummy aches, has started having wetting accidents, hurts when she urinates, easy bruising, constant pain behind her knees and general leg pain, cough, and moderate to severe fatigue that seems to be increasing. She has already been tested recently for UTI and has come up negative each time. Can you give me some ideas on what we may be looking at?
