Thanks for your question on HCM.
Since your pain is related to drinking coke and eating chocolate, I think isis due to hyper acidity. As both coke and chocolate can increase
gastric acid secretions.
And as a rule in left sided
chest pain, we need to rule out cardiac cause first.
So get done ECG. If this is normal than
stabbing pain must be because of hyper acidity.
Try to follow these steps for better symptomatic relief.
1. Avoid hot and spicy food.
2. Avoid large meals, instead take frequent small meals.
3. Avoid stress and
anxiety.
4. Start
proton pump inhibitor.
5. Go for walk after meals.
6. Keep 2 - 3 pillows under head in the bed.
7. Avoid chocolates and coke if possible.
