<s>[INST] I am 22 and was stung by a bee yesterday around this time. I was stung on the center of the sole of my foot. It was fine until around 10 pm last night when i noticed it was swelling and started to become painful. Over the course of the night it hasnt gotten any better. I am taking benadryl. Is the swelling normal this long after a sting? [/INST] Hi. Welcome to Chat Doctor . As you are stung by a bee on the sole of foot that has got swollen and painful, it is normal occurrence after bee sting and is due to allergic reaction or anaphylactic reaction with the toxic chemical released by the bee sting. It causes inflammation leading to swelling and pain. It can take at least 4 to 5 days to resolve and cannot resolve immediately after taking anti-allergics like Ben Chat Doctor. . You can continue taking Ben </s>
