welcome to health care magic
As told by you,,you have undergone cyst
removal operation and suffering from low grade fever
since 2 days..
Fever occurs because of inflammatory mediators which are released during surgery...
After the surgery usually your doctor prescribes anti inflammatory agents like paracetmol and antibiotics..
with the use of these drugs,,fever is unlikely to come...
Even after the using of anti inflammatory agents,,if you are getting fever consult physician and take suggestions from him..
hope you understand my suggestion..
