4 weeks ago I awoke with chronic pain in my neck, behind the right ear, just above the right shoulder on the front, on my right shoulder in the back. During the day the pain progresively got worse and could also be felt down the right side of my breast, and occassionally in the centre of my chest.. I have had an ultra sound on the thyroids, which showed no problem. My doctor said it was muscular, which I disputed. As a last resort I have been taking Amoxil for 4 days. The pain has eased, but I am more aware of localised pain now behind my right ear. I have a cochlear implant, and behind the ear feels sore. The doctor has checked inside the ear and can see no sign of infection. Although I did have signs of an infection 5 weeks ago before all this started. I took Amoxil then and that cleared up.
