Hi,
I am sorry that you had this
bee sting. Few things can be done now after 24 hours. You can apply ice packs locally for the pain and swelling to reduce.
Take anti-inflammatory drugs like
Tylenol for a day or two.
If the swelling is big then it may be incised and drained.
You need to give rest for some time and do not walk for a day.
Get well soon.
Regards,
