I take probiotics and zantac (ranitidine).Why do I have problems with acid reflux, swallowing capsules and trying to burp. Also my flatulance smell esp bad lately.

Need GI Consult. You have acid reflex not relieved by over the counter zantac, (ranitidine) which is not so uncommon.You can try Omeprazole a stronger acid suppresser available over the counter you also have flatulence problem which may have a different cause consult your doctor or a gastroenterologist to find the right therapy for your problem.
