Hi ... Noted you have blood in urine... First get urine examined for routine microscopic examination.. If pus cell present UTI is cause ...According to culture higher antibiotic might need. If only hematuria without pus cell and proteiuria present then glimerulonephritis might suspected... USG done for it and also for detection stone also...... If facial rash present then autoimmune disease also ruled out like SLE .... As thus can affect multiple system include liver and kidney both...... So if needed by surgeon biopsy might taken..... Meanwhile take low fat diet with more fruits.. Take care...... Dr.Parth
