On 17-5-15 evening my son had an injury in left pelvic bone. Docter didn't put any plaster cause that was not possible due to inappropriate space. Docter started few calcium tablets, vitamin d sachets and pain killers. An x-ray exactly after 20 days of accident was showing not such improvement as per our view but docter said that bone is improving and bone marrow is developing. Now after more than one month of accident docter tried a little walk on my son and he felt gud but there is some stumble in walking style. What should we do now.
