Thanks Doc Martin for reminding me about the Carotid artery.
In turn this reminded me of what Dr Jemsek said "Clinical Pearls" in Lyme Borreliosis Complex
'The sore throat that is not a sore throat' - What is Carotidynia?
Frequently our patients describe sore throats as part of their recurring symptom complex. Often, when specifically asked, the patients note that ear pain accompanies the throat pain, but the patients often state that their primary physician can find no reason for their discomfort. In fact, on examination, there is no sign of inflammation of the throat or ear.
