bruised and swollen finger

i was gardening yesterday and felt a pain in my middle finger, it felt like something was trapped and it proceeded to swell and turn a little bruised, the pain has now gone but almost all of the finger has now turned bruised and purple and is still swelled up, can anyone tell me what has happened and if I need to do anything about it??

Sounds like you got stung by a bee.  Some people have only a small reaction to beestings, and a few people get anaphalactic shock, but there is a third group that has a medium reaction to beestings, usually described as having the finger swell a little and turn color but then go down within a few days.  You might google "beestings" -- I can't remember the name of the third reaction, but maybe that's what happened and you're in that third group.

If you don't think this is it, possibly you bruised a tendon.
