I have gone through your query. Based on the information it looks like GERD. I would suggest you few measures that will be beneficial. Take capsule omeprazole 20 mg once daily empty stomach, before breakfast for a week. Avoid spicy and oily food for few days till the symptoms are resolved. Avoid or reduce the intake of meat, dairy products, and add more fiber to your diet. Eat lots of salads, vegetables, fresh fruits. Avoid excess consumption of tea/ coffee/ hydrogenated drinks. Avoid smoking and alcohol, if any. Eat frequent small meals instead of heavy ones and do not starve. Do not lie down immediately after food, walk for at least 10 to 15 minutes. Keep your head end slightly raised when sleeping. Maintain a gap of atleast 2 hrs in between dinner and going to bed. Eat light meals prepared under hygienic conditions. Avoid eating fast and talking while eating. Regular exercise is very much essential. Follow this measures your symptoms should reduce. Follow this measures you should be fine. If you have any further doubt, I ll be glad to help you out. Lump need to be examined to say what it is. So see local doctor for examination. Take care
