Help My Mother Get Treated

My mother underwent a surgery for the breast cancer in 2018 in bowring hospital and following that she underwent chemotherapy in kidwai hospital using cisplatin chemotherapy drug, post the the completion of 9 cycles she was fine as per doctor recommended, however she is now finding severe lower back and leg pain. Though it is a government hospital doctor advised us to take medicines through his reference which costed us 13 thousand rupees for per cycle,  am being her only son working in a bpo took personal loan for her treatment. However since now the issue is again started I don't have money to take her further treatment,  also I now left the job to take care of her at home since she is not able to walk due to the severe pain. I kindly request you to come forward and support me in any form to save my mother.
