Hi,
As currently there are lots of case of viral fever dengue etc and flu is coming. My advice would be to avoid combiflam.
Take paracetamol 500mg thrice daily. Tepid sponging in case of high fever, plenty of fluids.
Get few investigations done.
Complete blood count, Dengue NS1 antigen, and malaria antigen test.
A detailed history may help in guiding you better.
