Hello,
Pain in the sternum can be caused by muscle sprain,
acid reflux, collar bone or sternum injuries,
costochondritis. You can take antacids, PPI's like
Rabeprazole &
Acetaminophen (Tylenol).
Get physically examined, get X-Ray, CT, if required MRI done to rule out any injuries, hair cracks or fractures.
If sternum pain is persistent, associated with vomiting &
chest pain, it can be indicative of developing cardiac problems.
So, you need to see a cardiologist & get all tests done. Add fiber in your diet, stay away from addictions if any, avoid oily food.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Nupur K, General & Family Physician
