Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. You should not worry about. I will try to explain you something and give you my opinion. You should know that normal heart beats range between 50-100 beat for minute. If the heart beats over 100 for minute regularly than we talk about sinus tachycardia. Sinus tachycardia might happen for different reasons like simple emotional stress, coffee and energy Chat Doctor.  A flu or a bacterial infection might be responsible for sinus tachycardia because during infection our unitary system is activated, and the hole organism needs more supply, so the heart goes on tachycardia. Other symptoms like headache, muscle aches and dizziness are normal, they soon will disappear. So, don't worry, it will pass. Hope I was helpful. Best regards,
