Hi there ~
I understand your concerns. Suffering from cold
, feeling palpitations and symptoms of a viral illness can make you lethargic while keeping your blood pressure normal. I do not believe that the palpitations are due to the cold or cough
. However you may have an anxiety
disorder that is making your system act up this way. I hope you take adequate rest, hydrate yourself enough and eat right and regularly to fend off the illness. I hope this helped reduce your anxiety.
I hope this helps. Take care of yourself and have a lovely day!
