Thank you for your question!
I understand your concern. Your symptoms seems to be due to viral infection. There is nothing to worry. It will subside in 1 to 3 days.
You should take Tab. Paracetomol thrice daily until fever
subside and Tab B complex once daily. Keep taking more fluids.
If condition do not improve in 3 days with above medications, blood tests may be required. So, if no recovery, its good to meet your physician.
Hope you fast recovery. Thank you.
