Hello doctor I'm feeling pin like pain in my chest and my back in January I feel so much pain in my chest bt now I feel pin like pain on my chest  I check my ECG which is normal kindly suggest me for better precautions

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.
