Hi welcome to HCMForum. Human body is a complicated machine.
There is a term idiopathic means un known cause. It is clearly
written in text books as the last cause of the disease. so now
the temperature may be idiopathic or there may be some resi-
-dual infection in deeper layers of tissues. Dehydration
other possibility. it may be corrected by its own in a short time.
Besides i advise you some diet recomendations as Give plenty of
water fruits and juices to recover from dehydration. Give more
of green leafy vegetables pulses sprouts to build general health.
wishing for a quick recovery. thank you.
