Answers:
For a mild disorientation (101 or below), later no. If you own a lofty restlessness, or one that last for more than a few days, they yes
Any frenzy over 102 and/or one which persist for more after two days.
Whenever you suggest that the hallucination is not going down, and your body heat is too giant. Also, if you enjoy ache and pains anywhere in your body, or if you hold convulsions, or own come out near a unwary.
Just depends on how giant the frenzy is. If the hallucination is below 101 degree next no, unless it is persistant for a few days. Because you may hold a virus or something and most virus will travel away on their own next to within a couple of days. If the disorientation is 101 or complex later yes. If the restlessness is 103 degree or big desire Emergency Room support.
