The trouble started when my father had a minor fall from a two-wheeler, around a month ago. Since then, he is having pain while moving his arms which then progressed to acute backache and now even his legs. He is not able to walk or stand for more than a minute at a time. I also noticed a throbbing nerve near the knee area of his leg. We have consulted two different physicians- one an orthopaedist- but to no avail. There is very little improvement, if any. Please advise as to how should we go ahead with any further treatment.
