I have lower jaw pain and swelling for one and a half months. Had sinus infection. Got antibiotics from doctor. Sinus cleared up. But the jaw pain and swelling still there. It hurts to touch under the ear. ( Where the jaw ends). Have swelling and hurts to touch. Pain constant throughout the day and night. Feel like sore, scratching pain. Swelling same for past one and a half months. For last 4 days, top of the neck feel so tender and painful. It's little swollen and feel sore. It's on top of the neck where the jaw ends under the ear. Only right side I have swelling. Why it's hurts to touch under the ear and it radiates to the neck. What could be the issue?
