Hello, Welcome to HCM and thanks for asking your question. I can understand your concern. I would like to tell you that in most cases, by the age of 21, most of the bones fuses and bone growth will not occur further. You are already 21 and so there are very rare chances that your height might increase further,but don t give up. As your doctor said, so there are still very less chances in few months that your height might increase by few centimeters. So do take protein supplements, drink milk, take healthy food containing vitamins and minerals and above all do regular exercise to raise your height. You can continue taking rolsical plus and cobodex tablets daily, which helps in bone growth, because it contains vitamin D and calcium, which helps in mineralization of bone. Hope this will help you and feel free to ask any of your further queries.
