I'm really worried about my mom. She had CABG surgery about four months ago, and ever since, she's been dealing with a dry cough. I recently had her get an X-ray, and luckily, it showed everything's normal. But I'm still concerned. Is this something we should be worried about? Could it be related to her surgery or is it something else entirely?

Since your mother's X-ray showed everything is normal, it is less likely to be a serious issue. To help alleviate the dry cough, you can give her a cough suppressant like Delsym (dextromethorphan) 30mg every 6 hours as needed. Additionally, she can try using a humidifier at home to keep the air moist. If the dry cough persists or worsens, it would be advisable to consult with her cardiologist for further evaluation and management.
