My mother had fluid in her lung, and her primary doctor sent her to Dr. Khashayar. He had done additional tests on her, everything was negative. HE could not diagnosis my mother with pneumonia. I thought he is specialist in pneumonia. He did not give her any medications either. He could not treat my mom’s symptoms. Then he asked for help from Dr. Joshua D. Perlroth infectious in walnut creek, if he could find out what was wrong with her. Dr. Perlroth after 5 min. reviewing my her records he said its either TB or Cancer. We took mom to Stanford hospital, their doctors told us she has pneumonia. Both Dr. Khashayar and Dr. Perlroth need to go back to school and study more before they practice and disturb patients. I do not understand these 2 doctors have lack of knowledge or malpractice? Do Not trust these 2 doctors at all.
