[|Human|] My dad fainted over 3 weeks ago and hit his head on his way down, since then he has had a very stiff neck and describes a crunching noise every time he slightly moves it. He has been applying Voltaran for temporary relief, and Ibuprofen/Paracetamol - however the pain seems to persist. He will have it properly examined when he returns home from travelling, however would you have any suggestions that may give him more relief? Does this sound as if it is whiplash or something more severe?
[|AI|]  Hello dear, Since your dad is having stiff neck along with crunching noise on movement following a fall, some bone injury(obviously minor) is likely. You please get an x-ray, and get it examined. Meanwhile, applying a cervical collar may help a little. And, minimize neck movements and avoid extremes of movement(very important). Most of such minor injuries can be managed conservatively though it may take few weeks for complete resolution. I hope you will find this information useful. Thank you.
