91 year old Mom has what was an intermittent pain radiating from her right cheek area to her right eye, it has now become constant. She is unable to chew because the pain becomes unbearable and has also lost her appetite. PMH: glaucoma-fully controlled, pulmonary fibrosis, arthroplasty r/l hips-r knee-l shoulder from degenerative OA, high cholesterol. What could this be? Not relieved by ice, heat, NSAIDS, or. Percocet. I have her drinking Boost High Protein as of tonight, she has not been able to eat for 2 days and just told me. Also would neurology be the specialist of first choice to see? Hoping someone has hours available tomorrow.
