<s>[INST] Hi,I have a sharp pain under my ribs on my left side and breathing is shallow I m in bed when I get up I have to roll to my right it eases pain some or a lot when trying to lift up to get out of bed I can hear my heart beat and bubbling and gurgling, it all started last night when I sneezed and I was already uncomfortable cause I ate so much watermelon felt I would pop and I have hiatal hernia just saying Thank you [/INST] Thanks for your question on Health Care Magic. I can understand your concern. By your history and description, possibility of acute gastritis and related pain is more. But better to get done ecg and 2d echo to rule out heart diseases because left sided chest pain is commonly seen in heart diseases. If both these are normal then no need to worry for heart diseases. You have hiatus hernia. And due to over eating you have acute gastritis. So better to avoid large meals, instead take frequent small meals. Avoid stress and tension. Avoid hot and spicy food. Start proton pump inhibitors and prokinetic drugs. Go for walk after meals. Don't worry, you will be alright but better to first rule out cardiac diseases. Hope I have solved your query. Wish you good health. Thanks. </s>
