I have a problem with my jaw its hard too explain occasionally i will put of nowhere become uncomfortable with a feeling that something has fell out of place its on the right side where the neck and jaw join it happened 1jr and now my jaw aches?

I'm unable to come up with a differential diagnosis for your symptom, but I recommend consulting an oral surgeon for a thorough evaluation

You will need to be examined and imaged to arrive at a diagnosis and thus appropriate treatment plan. You may have Jaw joint anatomic and/or functional dyscrasia, TMD (Temporomandibular dysfunction), in which case you need to see Oral Surgeon or Oral Pathologist. May coincidentally and/or concurrently have a malocclusion (bad bite) and therefore need to see an Orthodontist.
