Since yesterday I've noticed reddish brown ting in my daughter's urine. She did not complain of any pain though. A week ago there was an episode where she cried profusely and coughed out fresh blood. She has a chronic constipation and always gets some or the other insect bites and itching and bleeding. Occasionally complains of headache and belly pain. When I put this all together it scares me a lot. Do you think all these symptoms point to anything serious?
