I have severe headaches at the base of my skull. I am having difficulty with some swallowing, it is impossible to go up stairs without holding on to something. I am forgetting more words and now my left arm is going numb. I saw a neuro who thinks I have anxiety about stairs! She finally agreed to a CT scan, but will that catch what is going on in the base of my skull?I saw a neuro who thinks I have anxiety about stairs!
