So 5 weeks ago out of the blue I started getting these strange head rush type feelings, not very nice. Went to doctors had bloods all ok. Mini ecg was ok. All vital checks ok. Then I started having these every day here and there until one night I woke frantically with pins and needles, head rushes and very scared. Thought I'd faint. Called 111. Didnt go to A&E. Next day more tingles / rushes in head and then another attack really awful that lasted ages, woke me from sleep. Still ongoing and very scary. Doctors have no idea and been lots. Had more bloods and nothing showing up. Got mri Tuesday. Going crazy and scares me at night. Also notice horrible sensations when try nodding off. Feel tired, worried & at a loss.. Anyone experience anything like this? Seems neurological but dont know?
