Hello,
U didn't mention about other symptoms apart from fever... if yes, then kindly do mention it .
As mentioned by ur doctor it could be due to anxiety & also other precipitating factors too
Next Steps
u can take paracetamol 500 mg symptomatic ... followed by good rest... keep yourself hydrated..and there's nothing to be anxious about..just keep ur mind calm and relax
Health Tips
u can contact ur doc or ask for my suggestion if the temp donot subside even after taking paracetamol..
take care
