Hi there, i have a question concerning my mum. She is 68 years old and recently had weird unexplained symtomps, such as frequent fever, increased responsiveness towards cold which can lead to extreme shivering, then extreme sweats. Recent blood test results shows that her hemoglobin has decreased to 6.7. Other concerning results were high levels of uric acid, ureum and creatinine. Her gp thought it was a thyroid, but a test has been done and proof that the ts4 and tsh (not sure about the name exactly) are normal. She was sent to hospital to get blood transfusion, then sent home with 10.7 hemoglobin. Week after she started to look pale and feel cold most of the time, she decided to get another blood result. Hemoglobin decreased again to 7.8. We are clueless of what is happening to my mum. Also, forgot to mention that last month her feses came out black, even though its back to normal now. The black feses and stomach/gastar discomfort caused her to question about her health. Please help!! Thank you in advance
