Owen: I don't know if you are still following this thread, but I must share my daughter's encouraging experience with you. She's now 15 and for over a year she had PCS symptoms including debilitating headaches, dizziness, extreme fatigue and lethargy, difficulting focusing and concentrating, light and sound intolerance. Notice I said HAD...Her doctor prescribed a low dose of Effexor XR to promote neurogenesis and I was able to finally convinced her to see an acupuncturist. Within 3 weeks her symptoms cleared up by at least 90%. The acupuncturist said that blockages in her upper back and neck were impeding blood flow to her brain, causing her symptoms. I don't know how it works, but I can tell you that it DOES. For the first time since this nightmare began I am confident that she'll be able to live a normal life.
