Thanks for the query to H.C.M. Forum.
After rest ( complete bed rest
) of 7 weeks (approximately) , you worked very hard ( exertion ) and you get pain and chills
After whole day rest again pain and temperature.
In my opinion this is not a case of any tear of muscles ( c section ). Fever
, pain & chills may be due to ,
urinary infection or malaria
( tropical region).
Still fever occurs than get blood work done for C B C, E S R ( Malaria parasite),.
Urine for infection.
Till use paracetamol
650 mg as requires.
