I received my decompression surgery almost 2 years ago, but am still experiencing severe headaches, nausea, vomiting, and pins/needles in my hands and feet. During my surgery I received a laminectomy and duraplasty, but my cerebral tonsils were not shrunken with a laser. All my post op scans look normal, but i am still extremely symptomatic of Chiari and really need advice. No pain meds help the headache, and it is constantly there - can range from a 5-10+. Worsened with exertion and valsalva maneuvers. SOS! has anyone experienced this? If so, what helped you?
