My DD 4yrs had Chicken Pox about a month ago. She has physically recovered but is ridiculously tired. Sleeping 12 hrs every night and wanting to sleep in the day. Screaming when going to nursery and generally weepy. This is unlike her and awaiting tests on urine and faeces from docs in case there is anything else. Is it possible to have this reaction post virally this young? I am getting really concerned, has anyone else experienced this or is the chicken pox just a coincidence? Advice please!
