I have always had a resting heart rate of around 60 but it has currently been between 80 and 90 the past few weeks. I am recovering from a virus. 2 weeks ago, I had a fever that lasted a week along with a headache, dizziness and lethargy. I feel fine now with the exception of needing a lot of sleep. Could my high heart rate be related? I cant see my GP until January? I never had congestion along with the fever but after it broke, I developed a dry cough when I  inhale deeply. It also hurts a bit along with the tickle during inhalation. Thanks.
With increase in fever, there is proportional increase in the heart rate. This is normal physiology of the body. If it does not rise, there are again different cause for the same. So don't worry, once your body will completely recover your heart rate will come to normal. Take adequate rest and maintain HY Chat Doctor. That will help you to recover fast.
