Thanks to all for your feedback! Perhaps I'm using the wrong term re intracranial pressure. I was using it to describe the pressure/tightness I feel in my head with or without a headache. Yes, my neurologist at my large university setting does know about my chiropractic treatment and approves of it. It comprises 15 mins of electronic stimulation with an ice pack on my neck, 20 mins of ultrasound on my neck and mild adjustments. I don't want to jinx myself, but all of the sudden, I've had 4 symptom free days in a row! Is it possible symptoms to stop all at once? Thanks again!
