It is possible that a more serious underlying condition causes the pain that you are experiencing. For this reason, it is important that you continue to follow up with your doctor to ensure that the pain is not caused by something more serious. Your doctor may recommend further testing, such as an MRI or CT scan, to better understand the cause of your pain. It is also important to watch for any other symptoms that may have developed since the pain began, such as shortness of breath, difficulty breathing, chest pain, or palpitations. These symptoms may indicate a more serious problem.
