Your symptoms of stomach burning, eye irritation, and fainting, along with a mildly elevated ESR of 27, require a proper medical evaluation. Fainting sensations must be investigated by a doctor to rule out dehydration, anemia, or blood pressure fluctuations. For temporary relief of stomach burning, an over-the-counter acid reducer like omeprazole or famotidine may help. For eye burning, preservative-free artificial tears can provide soothing relief. Please avoid self-medicating for the fainting spells. I highly recommend consulting a healthcare professional for a physical exam, blood pressure check, and targeted blood tests to safely identify and treat the underlying cause.

Since your acidity has lasted for six months, it is highly recommended to consult a doctor for a proper evaluation. For temporary relief, you can use over-the-counter antacids or H2 blockers like famotidine. Proton pump inhibitors (PPIs) such as omeprazole or pantoprazole are very effective for chronic acidity, but they should be taken under medical supervision. Additionally, try making lifestyle adjustments: eat smaller, more frequent meals, avoid spicy or fatty foods, limit caffeine, and avoid lying down for at least two hours after eating. Please visit a healthcare provider to get a personalised, safe, and long-term treatment plan.
