Hello,
I have gone through your query and understand your concern.
There are many causes for Pain in Xyphoid process area.
As you suspect, it may be due to anxiety.
But some other important causes like
Coronary heart disease, Angina,
peptic ulcer, Gastro Esophageal Reflex Disease (GERD) to be ruled out.
In fact, anxiety may trigger the Angina, Coronary heat disease or
gastric acid secretion.
Thus you need thorough medical examination and further investigations to find the exact cause.
1. Upper GI endoscopy
2. ECG
3. Ehocardiography
Depending on the cause, the treatment varies.
If it is due to Ulcer or GERD, then
Proton pump inhbitors like Pantaprazole will be felpful
Try
relaxation techniques like yoga and meditation.
Exercise regularly.
DO not skip meals and have proper non spicy diet.
Hope this helps.
Wishing you good health.
