It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. If you are overweight, it would be helpful if you could lose weight. for info: https://www.mayoclinic.org/diseases-conditions/heartburn/symptoms-causes/syc-20373223#:~:text=Heartburn%20is%20a%20burning%20pain,and%20no%20cause%20for%20alarm. Wish you good health!

Your symptoms are more characteristic of GERD. Omeprazole dosage may have to be increased. Avoid spicy,oily foods,alcohol, caffeine, nicotine, aspirin& meds like advil or aleve. If you note no improvement, it's time to consult a gastroenterologist for evaluation, appreciate testing & proper treatment.
