My sister has been to the ER with symptoms of tingling/pins and needles almost burning sensation in her left side of her face and head. She also had a plugged ear. Dr checked her over and can t find a cause. She was referred to an ear nose and throat specialist who found nothing wrong in her ears. Now referred her for an MRI. This has now been 4 days since it started. They ruled out stroke but everyone seems confused. I very seen things like it could be an allergic reaction or migraine but could those last 5 days ?
