my daughter received her first shot in August of 08. Within 2 weeks she had a terrible bout of thyroiditis which translates into hypothyroidism;very tired and fatigued. A few months after that severe dizzy spells, racing heart and seeing stars in the middle of the night. Then migraine like headaches. Now chronic nausea and tingling and pain in her chest, shoulder and arm. Recently diagnosed with Parsonage-Turner syndrome which produces neurological impairment from "viral infection". The impairment is supposed to improve over time. She has had a hellish year. How is it that a 19 y0 girl who was healthy and a runner has turned into what doctors now think is a hypochondriac?
