I'm a bit concerned because my heart rate is around 60 to 55 when I'm lying down. Is this something I should worry about? I've been having mild pain on both sides of my chest, which feels like muscle pain, and it comes and goes. I had an ECG in May, and it was normal, and I just had a Chest CT scan, which also came back normal. Do you have any advice on what might be causing this, or should I look into it further?

It's good that your ECG and Chest CT scan results are normal. Your heart rate of 55-60 while lying down is within the normal range for adults. The mild chest pain you are experiencing could be musculoskeletal in nature. You can try taking over-the-counter pain relievers like Acetaminophen 500mg as needed for the chest pain. Additionally, you can apply a topical pain relief gel like Volini gel on the affected areas. Make sure to practice good posture and avoid activities that worsen the pain. If the pain persists or worsens, it's advisable to follow up with your healthcare provider for further evaluation.
