I’ve had 2 or 3 CT and 2-3 MRI of my brain the past 2-3 years. I never really had constant headaches but I had cysts and neuro symptoms that freaked me out (twitching weakness etc). Last MRI was 2020 normal and last CT was April 20th also normal. On going lightheaded falling feelings since January every day especially mornings and trying to sleep. Now over last 4 weeks headaches and hot flashes. I’m beginning to feel insane because I wanna push for another MRI. I have a history of anxiety from heart palpitations been to like 3 cardiologists and had a boat load of testing. The head sensations are unbearable any advice? Would ct in April rule out anything?
