Suggest Remedy For Difficulty In Swallowing Every Time While Eating

At the begging of this year I started having problem's swallowing when I would first start to eat a meal every now and then. It would feel like I was starting to chock on my food but I was still able to breath. This feeling would either pass by me throwing up or I would go through a minute of pain as the food would make its way down. Now however I am having this problem every time I eat. So I was wondering is this a serious problem or can I wait until I get my medical?
