question: My cousin has developed a curvature of the neck. I don t see her often so to me it was quite noticeable that it had become more pronounced. Looking at her face on, the curvature is a C curve bowing to the left. I also noticed she doesn t turn her head to the left but turns at the waist. She tells me that after 4 hours sleep she is awakened with a severe headache. No c/o seizure, vision difficulties but have noticed she may not hear as well on that side. She is about 5 3 and 130 pounds.
