The mind is a very complicated thing and, sometimes it does strange and unfamiliar things. I have experience a similar kind of pain because of my brain injury. Your pain may be your brain over reacting to unbalanced stimulation of your auditory system. This pain can be evaluated if you see the right kind of doctor. You would probably want to start with a neurologist. Depending on where you live, a pain specialist would be even better. Also look for medical studies in neurological pain where you might find a study you can participate in.

If you don't have the resources to find these kind of specialist, ask your family doctor about a drug called Gabapentin which is a generic for Neurontin. It's a commonly used drug that helps quiet down the misfiring neurons and nerves. It is often used by people with brain and nerve injuries for pain control.
