Hi, My sister is experiencing very bad headache and no medicine seem to reduce it for the past two days. Now she has developed stomach pain too. She also experienced blood loss through her stool too. We have taken scans and blood tests to figure out the reason but everything seems to be inconclusive. Please suggest some way to diagnose the problem or even reduce the pain. No medications seems to be working for the pain. I have attached documents regarding the blood tests and the chest scan done..
