My head is has changed shape and developed a sort of ridge I guess for lack of a better word that runs horizontally across the lower back of my skull. At first I thought I was insane for thinking my head felt weird, but my husband was playing with my hair/rubbing my head and noticed it as well. What could cause this? I also get headaches frequently...I actually have an appointment with a neurologist in a couple of days to do an expanded visual acuity test and go from there. Could the head shape change be related to the headaches? What should I be asking the neurologist about/what to look at?
