My RD finally decided the Methotrexate/Plaquenil combo wasn't doing much so
he added Enbrel to the mix three weeks ago.  The first two weeks were fine -
no reaction, but this last Thursday I got itchy all over, but no rash was
visible, and I had a weird tight sensation behind my ears and in the back of
my neck.  It lasted about an hour or so and then went away.  No problems
since.

Strange?  Not so strange?

About how long does it take for the Enbrel to kick in.  Weeks?  Months?

Thanks for any input.
