Ok, im not sure what my sister has or what is wrong with her, but..My little sister is 16 she has dropped alot of weight she was already small but now is down to a size 0. She is very pale. She went to her doctor and they did some blood work because they found protein and blood in her urine. The doctor called my mom monday and wanted to see my mom and sister IMMEDIATELY but my sis was gone at the moment and they could not go in so the doctor said for them to come in 1st thing thursday morning (tomorrow) and they would see them 1st they would not have to wait. That it was urgent. It's really got me worried. I looked up protein/blood in urine and lots of thing come up, HIV, luekimia, bone marrow cancer, pregnancy, kidney cancer, diabetes..etc. I will find out tomorrow but im so worried anybody have any idea what it could be?
