Should I get a CT scan for pineal gland cysts or tumors if I have frequent headaches, severe migraines, trouble falling asleep, non-restful sleep, vivid dreams, no circadian rhythyms, nausea, vomitting, seizures, dizziness, trouble concentrating, sensitivity to light, and vision problems? Or could this be related to something else? I am a 20 year old female, 5 1 , 130lbs
