Hi welcome to Health care magic forum. It appears that you are about to get
fever,these symptoms seem to be prodromal symptoms. These also could be due to gastric irritation of the fever or due to diet.
I advise you to consult a physician for diagnosis and treatment. You may need to have blood tests, like D.C, T.C, E.S.R,
WIDAL, Q.B.C etc along with other routine tests.
Avoid taking spices, chillies, junk foods, and oily foods to avoid
indigestion and burning in the stomach which some times is not felt, but is there.
Avoid taking potato, other tubers, cauliflower, and coconut to avoid body pains .
Wishing for a quick recovery and thanks for calling.
