Today I noticed a dull pain on the top right side of chest when take deep breath. Could it be just pulled muscle? Need to worry? What meds will help?

see doctor now. Any pain when taking a deep breath can range from a muscle spasm to an actual lung or heart condition. If it has lasted for at least 48 hours and has not fully subsided or is getting worse and interferes with any normal daily activities you need to immediately go to your nearest urgent care or emergency room. You can contact your doctor/nurse if you have one if it is manageable.
