I would have your ear checked again to see if the infection as gone.

How can neck problems affect tinnitus?
Long-term pain and discomfort from conditions in the neck can also aggravate tinnitus in the same way TMJ problems do. Studies have shown that patients who have suffered an injury to the head and neck region, such as from a car accident, or who have neck pain or stiffness for other reasons, such as arthritis, are more likely to experience tinnitus.
Furthermore, there is some scientific evidence to support how the nerve endings in the neck make connections in the hearing centres of the brain, explaining how neck problems may affect tinnitus. Quite often the tinnitus associated with neck injuries may be more severe, and can be combined with other symptoms such as headache, depression, and problems with memory and concentration.
Treatment generally depends on the cause of the neck problem, but the results from treating the underlying neck problem are often good. Treatment options can be discussed with your family doctor, who in some cases will recommend simple measures such as the use of painkillers and physiotherapy. Some people are able to modify their tinnitus by moving their neck. Recently, it has been suggested that in a minority of these individuals, TENS (Transcutaneous Electrical Nerve Stimulation) can help them with their tinnitus.
