Have you tried the Mayo Clinic in Jacksonville? Their appointment phone number
By the way, where is the pain? Is it located more to one side? If the pain originates from the back of her head, she is probably deang with occipital neuralgia (ON). I've been fighting ON for 30 years (I'm 47 now), and I've had multiple surgeries, injections, and have taken many dozens of medications over the years.
Right now, I take Cymbalta, Lyrica, Keppra, and Lexapro, along with Suboxone.
