<s>[INST] Hello, I ama 54 year old woman of average height and weight with no major medical issues other than recurring vestibulopathy (cause is unknown, but has been thoroughly investigated).   I was bitten by a very tiny (about as long as a baby fingernail and as thick around as about 10 pieces of thread put together) grey worm a week ago.  The bite was very painful when it occured and hurt for about an hour afterward.  Now the bite is itchy and is about the size of a quarter.  Is this something I should be concerned about? [/INST] Hi,from history it seems that there might be having local allergic reaction due to poisonous bite.Take antihistamine like Cetrizine, Levo-cetrizine or Benadryl medicine for 3-5 days.Apply triple action locally.Ok and take care. </s>
