I've a feeling of heartburn and acid reflux since last one week. It causes severe headache and heaviness around eye socket. Anything that I eat or drink comes out as vomit. Tried treating it with reducing amount of food intake, no spicy food, home-made treatment (black salt, methi, giloy etc.) & tablet also (acilock), but it's not working. Also, I get a sensation of emptiness in my stomach. This condition has happened in past also, but this time it has become very prolonged. Any suggestion on this?
