Pediatric paralysis begins with symptoms such as fever, headache, nausea, vomiting, dry heaves, and general discomfort. Parents often believe it is a cold or indigestion. After 1-4 days, the fever may subside for a few days but then return and be higher than the first time. The obvious manifestation is hyperalgesia, with pain that does not allow others to touch, accompanied by facial redness, headache, sore throat, dry heaves, and polydipsia. After 3-7 days, numbness may occur, commonly in the lower limbs. If not treated promptly, numbness can gradually and completely recover.
