We are on vacation and need to know if my 5'5", 115 pounds, 12-year-old son needs to see a dr. He slept restlessly last night, currently has a 100.3 temp and headache, complains of a sore throat in the evenings and upon awakening only, and his thumbs, forefingers and both legs feel like jelly. I am confounded by the last, never experienced that before. Should he see a dr. or can he just rest in bed? Jeanine Olswang
