I ve been sick for 4 days with different types of symptoms
Thanks for your question on Chat Doctor. I can understand your concern. No, I don't think this is right diagnosis. In my opinion, we should first rule out arrhythmia (rhythm disturbances in heart) in your case. Arrhythmias like atrial fibrillation, atrial flutter, supra ventricular tachycardia etc. can cause palpitations, dizziness, headache etc. So consult cardiologist and get done blood pressure monitoring, ECG, 2d echo and Holder monitoring (24 hour continuous monitoring of ECG). You may need anti arrhythmia Chat Doctor.  Don't worry, you will be alright. But first rule out arrhythmia. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
