[/INST] Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. I will try to explain you something and give you my opinion. You should know that fluttering sensation are related to rhythm issue. There are some electrical impulses that generates from parts of the heart different from normal sinus rhythm. They cause premature heart contraction, and you feel like escaped beats, filtering sensation. You might also experience light head, difficulties in breathing deeply. The causes of this rhythm issue might be different to emotional stress, coffee or energy Chat Doctor. The fact that you are diagnosed with a sinus infection might be responsible for your headache. An active infection in the organism might be the reason of the rhythm issue and related symptoms. So, if I was your treating doctor I will recommend some examination like a cardiac echo to evaluate heart function and walls, a full blood analyze to exclude anemia, hyperthyroidism, electrolyte imbalances and of course a holder rhythm monitoring to evaluate your rhythm tendencyAfter all this we can better judge what we are dealing with and how to treat it. Hope I was helpful. Best regards,  </s>
