Hi, I am 28 yrs old. I have been having pain behind my right ear on opening my mouth fully for about 2 weeks now. I do not see any redness or swelling surrounding the jaw or ear, the pain seems to be internal. I have no problem with my teeth or gums either. When I try to open my mouth fully, the pain is very severe and also, I have headache, the pain is near the eyebrow and behind my neck. I have on and off fever and chills and also nauseousness and dizziness sometimes. My hearing in the right ear is normal and no infection either. Please let me know exactly what it is related to and what doctor shud i seek if needed?
