I'm experiencing this sharp, pin-like pain in my chest and back. It was really bad in January, but now it's not as intense, just feels like pins. I had my ECG done and everything came back normal. Can you tell me what precautions I should take?

Given your symptoms of pin-like pain in the chest and back, and a normal ECG, consider consulting a cardiologist to rule out conditions like pericarditis, costochondritis, or gastroesophageal reflux disease (GERD); in the meantime, avoid heavy lifting, maintain a healthy weight, manage stress, and avoid triggers like spicy or fatty foods that can exacerbate symptoms.
