Q. I have been suffering from neck pain and vertigo symptoms (headaches, dizziness and nausea) since early May 2009. It was first thought that I had an inner ear infection however,due to the severity of neck and shoulder pain, it was thought that it may be delayed onset of whiplash following a car accident (rear collision) at the end of March. I have seen a physiotherapist and acupuncturist whose treatment of whiplash has proved ineffective and has not yielded longterm results. In the meantime I have developed a problem with my teeth; I cannot bite properly without making a loud squeaking noise. My jaw is tense and clicks. I pointed this out to my dentist when having a wisdom tooth removed and she agreed that this was not normal and said that she would refer me to a specialist. Having read up on this I am confident that I have TMJ, which has developed/been exacerbated by whiplash. My question to you is therefore this: how is TMJ diagnosed? Do I see my dentist or wait for a neurologist appointment?
