I'm really concerned because I was told my ECG showed NSR incomplete, and I'm experiencing some weird symptoms like heaviness in my head, weakness, lower back ache, mild chest pain on the left side, and even some gastritis. Could this all be related? Should I be worried about how these symptoms are connected?

Based on your symptoms, it is important to address each issue individually. For the incomplete NSR on ECG, it may indicate a potential heart rhythm abnormality. To help regulate your heart rhythm, you can take a beta-blocker like Metoprolol (25-50mg) once daily. For the heaviness in head and weakness, it could be related to your blood pressure. You can take Amlodipine (5-10mg) once daily to help lower your blood pressure and improve blood flow. For lower back ache, you can take Ibuprofen (400-600mg) every 6-8 hours as needed for pain relief and inflammation reduction. For the mild pain in the left chest, it is important to rule out any cardiac issues. You can take Aspirin (81mg) daily to help prevent any potential clot formation. For gastritis, you can take Omeprazole (20mg) once daily before breakfast to reduce stomach acid and alleviate symptoms.
