Treatment is mainly deptrend on the cause but you may take symptomatic treatment meanwhile. You can continue to take clomid which you are takoing already. Take antacids like h2 blockers (ranitidine) or proton pump inhibitors (pantoprazole or rabeprazole) will help to reduce excess acid production in stomach. You can also take digene gel or liquid or ulcero-protective agents like sucralfate or bismuth subsallicylate to reduce the burning sensation.
