Thanks for your question on Health Care Magic.
I can understand your concern.
In my opinion, you are mostly having stress and
anxiety related symptoms.
Stress and Anxiety are the biggest risk factors for
acid reflux and tension
headaches.
So we should first treat your stress and anxiety.
So
consult psychiatrist and get done
counselling sessions.
Try to identify stressor in your life and start working on its solution. You may need anxiolytic drugs too.
And beta blockers are known to reduce anxiety, so no harm in taking it.
For your chest symptoms, along with antacids, you need to follow these lifestyle modifications.
1. Avoid hot and spicy food. Avoid large meals, instead take frequent small meals.
2. Keep 2 - 3 pillows under head in the bed to prevent reflux.
3. Loose weight if you are obese.
4. Quit smoking and alcohol if you have these habits.
Don't worry, you will be alright. Avoid stress and tension, be relax and calm.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
