3 years ago a 10 kg weighted sound box fell into my sisters head , at that time we consulted one doctor and told no problem with the x-ray.after 6 months from that she is having heavy pain . Until now she is having heavy deadly pain . She is thyroid patient by birth . She is wearing collar also . Please reply.

She has been in pain for the last 2 1/2 years, and you haven't taken her back to a doctor?
We can't possibly advise other than to have more testing. X rays don't show everything!
