Hi, Pain below sternum
, rib-cage at bra line can be due to a condition called Costochondritis
wherein there is inflammation and hence the dull pain.
Pain at the lower sternal area can also be due to gastritis and GERD that is gastroesophageal reflux disease
There is reflux of stomach contents in esophagus and burping causes this to occur causing heartburn.
Nexium will help only to reduce the stomach acidity and symptoms related to it.
For stopping burping and reflux you need to add on motility regulators like Metoclopramide
. This needs a prescription.
Also take antacids when on empty stomach.
Go for soft bland diet in small frequent ways.
Avoid stress and anxiety as these can cause burping as well as costochondritis.
Apply local rubefacient liniment over the affected area to get soothing. You may take stomach friendly analgesic for costochondritis if needed.
Hope I have answered your query. Let me know if I can assist you further.
