In addition to the possibilities of asthma
, chest infection
which have been ruled out by X Ray etc, another possibility is GERD(gastro esophageal reflux disease/gastritis
). You might need to take a course of pantoprazole/omeprazole
, if that is the case. It is possible that the stress(you said you were worried about your brother's son) could have caused GERD/gastritis.
1. I would advise you to have frequent small meals.
2. Avoid spicy,deep fried,fatty food and carbonated beverages.
3.Do relaxation exercises/meditation
4. Avoid sleeping/lying down immediately after a meal. Wait for 2 hours before lying down after a meal.
Hope this helps.
Please let me know if you need any further advise.
