My son is 14 yrs old and was diagnosed with Typhoid 15 days back.he was hospitalised for 14 days due to lot of infection.Now he is recovering but specifically at night whn his body gets relaxed he suddenly feels he is becoming weak, feverish, legs pain.He feels as if his hands are getting bigger, or people around him are going far. He is feelling sleeppy but not avle to sleep. Why is this happening, any idea? Whom to consult for this?
