If a platypus gets you with his spur how long does the poison hurt?

The platypus does not have a spur, it has a venom barb on its hind leg. The pain from a platypus sting typically lasts for several hours, and can be quite severe. In some cases, the pain can last for several days. The venom is also known to cause swelling, numbness, and nausea. In rare cases, it can even be fatal.
