Hello! Welcome and thank you for asking on HCM! I understand your concern and would explain that your symptoms seem to be related to an infection, probably a viral infection. Have you measured your blood pressure during these days? What are the values? What about your body temperature? Do you have fever? I recommend consulting with your GP for a careful physical examination and some tests: -resting ECG -chest X ray study -blood lab tests (complete blood count, PCR, sedimentation rate, fasting glucose, kidney and liver function tests, blood electrolytes, etc.) -blood bacterial culture -urine analysis -urine bacterial culture. Meanwhile I recommend taking plenty of fluids (water, juices) to avoid dehydration and avoid prolonged standing position or straining physical activity. Hope to have been helpful! Feel free to ask me directly at any time. Best wishes! Dr. Iliri
