I am not sure if I have high or low intra-cranial pressure after a blow to the head over three years ago. Symptoms include back of head and neck pain, breathing problems (especially on waking), brain fog and insomnia or sudden sleepiness as well as reactions to food and drink (less now that I’m taking Zantac and Zyrtec as recommended by Dr Diana) I can’t sit down comfortably as pain increases and I feel that I need to support my head with a collar. I saw a Neurologist to find out whether I have a spinal fluid leak and he suggested a head and spine MRI scan with dye and, if that doesn’t show anything, a referral to a Neurosurgeon so that they can drill into the skull to test pressure. This sounds very drastic and I would like to know if there is a less invasive way to tell if you have low or high pressure please. I am undiagnosed with EDS although it has been suggested. Other family members have ‘allergies’ and hypermobility so it’s possible.
