Don't be worried, it is a normal thing. I love spicy food very much and I always feel like tearing when I eat spicy food.
Most of us have runny nose and watery eyes when eating something hot, this is all because of the active component of chili peppers which is called capsaicin, and his is the triggering element that caused runny nose.
Also because our mouth and nose and eyes are all connected, when we have something spicy, the capsaicin thing can also irritate the membranes of the eyes, causing tearing. The tears drain into the sinuses and run out the nose.
