hiatal hernia

I was  wondering if someone could help me when I eat the food will not pass . It hangs up in my chest . Some time it will take up to 30 min to pass other time I have to make it come back up when I try to drink water to make it pass sometimes it will go down other times it just about chokes me so it has to come back up . Please someone help me .I have been on pain meds for about one year do you think that could of cause this to happen .
