Hello and thank you for posting your medical query on E health forum.
From the history provided, it seems that you have left sided upper abdominal pain that worsens with meals, you could be having heartburn due to excess acid production (Gastro Esophageal Reflux disorder GERD).
You might consider consulting your physician or a Gastroenterologist for a physical examination, which can help to evaluate your condition and initiate necessary treatment measures.
In the meanwhile you might consider taking over the counter antacids, which help to minimise the acidity in the stomach and resolve your symptoms.
I Hope this is helpful.
