Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.Forum.
You had pain abdomen,
chills, hot flashes, with temp of 100,2 nights ago,next morning was better. Next night again you had stomach pain,
nausea, head ache, in the next morning also.
It appears to be the symptoms of
malaria fever, or
typhoid fever, with stomach pain due to
indigestion of the fever.
I advise you to consult a physician for diagnosis and treatment. You may have to get blood tests done for confirmation.
Once fever is controlled all other symptoms will automatically subside.
In the meanwhile you take light diet, like bread, biscuits, milk, juices, etc for maintenance.
Wishing for a quick and complete recovery.
Best wishes.
