Hi, thanks for using healthcare magic
The elevated temperature will cause an increase in the heart rate
, it will normalise when the fever resolves.
Viral illnesses can be associated with fatigue
, muscle or joint pain and malaise
which you are experiencing.
You should continue getting as much rest as you can, drinking alot of fluids, using the paracetamol
as you need it (not exceeding the daily dose), add a cough suppressant and a mucolytic
( if the cough is wet) to your current regimen.
It may take , in some persons, a few weeks for a cough to resolve completely.
If after a few days , you do not notice any improvement you may want to consider visiting your doctor for assessment.
I hope this helps
