33 years old female, no major surgeries, no major conditions, only chronic sinus (2 balloon surgeries last couple of years). I have been having headaches over the last 6 -7 years, allergist ENT (I visited 2) both said headache should be revisit with neurologist , since I had changed medication multiple times. This headaches are increasing in intensity to excruciating especial when lying down, if lye by left side the pain focus there if I move to right side it gradually moves sides. I cant move my head heavily, I hurts way more. I sitting down more than 2 hours and get up get dizzy and see everything darker, it gradually goes back to normal after 5-10 seconds. Headaches used to go away with Tylenol but not anymore. Sometimes I also have neck stiffness but I crack it and feels better. Yesterday I had tingling/numbness sensation on my feet. Today I woke up with stiffness on my left arm (feels like carrying a heavy bracelet) if I move my arm towards the floor and up again, this stiffness increases like if there is something heave inside my arm. Please help me, what should I do?
