Welcome to HCM.
I understand your concern regarding your skin irritation and fever. Fever with chills
and rash are seen in some viral fevers like Dengue
and some arthropod borne diseases. This condition has to be confirmed by examination and lab tests. I suggest you get in touch with a GP nearby you for complete examination and subsequent lab testing. You can take over the counter painkillers for the body ache
and apply calamine
lotion over the tender skin.
But examination by a doctor is necessary to diagnose your disease and getting appropriate treatment.
